Read more about this topic on page 10. Editorial | 3 Dear Readers, Welcome on board. Once again, we are going to take you on a trip behind the scenes of some the world’s most famous and successful companies. In this second issue of our customer magazine at work, we will take you to the desert, where the iconic Porsche 911 raced down the track in Bahrain’s scorching heat. Another destination is Scotland, where Terex® produces a mining truck of gigantic dimensions. The journey will also take you to Italy, where Gessi, the exclusive interior design manufacturer opened its factory gates for us. What is it that powerful race cars, luxurious bathroom fittings and monstrous mining trucks have in common? They all rely on a technology without which modern life as we know it would be unthinkable, but which remains ­invisible for most people: adhesive technology. “This is the golden age of glue” writes the American author Bruce Sterling and continues: “During the past 30 years, there has been a silent revolution in adhesion.” In this issue, we give a voice to that silent revolution and open the door to our engineers in Munich and Dublin. They'll share their ­insights and experiences as a part of Sterling’s silent revolution. In our trend report, we follow up on this theme, taking an in-depth look at the history of maintenance, a topic closely linked to the development of sealants, adhesives and threadlockers.

The icons on parade are w the cars that make up the field of the Porsche 911 GT3 Mobil 1 Supercup. The Porsche 911 is a legendary vehicle and a physical symbol of brand awareness rivalled only by a ­select few. It is one of the few products that have become a globally recognizable symbol, like Coca-Cola. However, what is not as well known as the elegant, curved shape of the 911 GT3 that just raced by under the ­burning desert sun is this "minor" detail: the construction of the car relies on modern adhesive ­technology. In order to draw attention to this fact, Porsche and Henkel, with its strong Loctite brand, have engaged in a partnership to support the Porsche Mobil 1 Supercup. The Supercup competition is the overture to Formula 1, the most popular motorsport event in the world. ­Porsche Mobil 1 Supercup races are held on every ­Sunday ­before a ­Formula 1 race. After the opening event in the ­Kingdom of Bahrain this spring, ten more races in ­different ­European countries are scheduled throughout the course of the year. The Porsche 911 GT3 Cup cars, which only weigh 1130 kg, boast engines with 420 bhp and a top speed of 290 ­kilometres per hour. This lightweight ­co­nstruction is made ­possible using alternative materials like ­aluminium and composites, which is where adhesives come into play. Since aluminium and ­composites don’t lend ­ themselves to thermal welding, alternative solutions needed to be found. Porsche and Loctite® engineers worked together to find ­ xactly those solutions, in the race car as well as in the e ­series model 911 GT3. Loctite® products are used in the construction of the engine, the gearbox and differential. ­Porsche relies on the proven Loctite® durability when it comes to threadlocking and flange sealing, ensuring ­reliability of these vehicles even under extreme conditions like the heat of Bahrain. Loctite® 243 is used to secure bolts on the ­gearbox clamping plate, the fixing bolts of the oil spray tube inside the gearbox and fixing bolts of the ­sequential gear shift system. While Loctite® 574, a fast curing gasketing product, seals the two-part ­gearbox housing. The fixing bolts of the differential housing, the stud bolts of the gearbox housing as well as the fixing bolts of the oil pump housing and the bolts of the mounting frame of a pinion wheel shaft are secured with Loctite® 270. ­Loctite® products are also used for component manufacturing: ­Loctite® 270 for the tappet pins onto the wheel hub, and Loctite® 243 for the heat protection shield mounted to the brake caliper protecting electronic sensors from the brake heat. Loctite® is heavily used in the manufacturing of the ­vehicles, but it plays a part in their maintenance, too. At the ­beginning of the season in March, all 14 cars ­taking part in the ­Supercup were provided with a full set of ­Loctite® ­threadlocking, ­gasketing and cleaning products. The ­cooperation ­between the two companies goes a lot ­further than that, however. Engineers of the two firms are in ­constant contact and ­Porsche’s demands often spur ­innovation in the Loctite® labs in Dublin and Munich. Highlight Bernd Homberg is the Loctite® Sales Engineer responsible for the cooperation with Porsche Motorsports. “It can go both ways: either we have a new product and approach the Porsche engineers, they test it and check whether it’s helpful for them. Or, Porsche hits on a problem that can be solved with adhesive technology and they turn to us for ­assistance”. He explains the way the partners work ­together. “At the moment, Porsche is testing Loctite® 5188 as a gasket for the differential housing. When they were looking for a way to attach a stopper to the tank we were able to solve the problem with high temperature ­resistant two-component epoxy adhesive Loctite® Hysol 9492,” he continues. | 5 This commitment to the high-end of innovation and ­quality represents only two of the values that Henkel and Porsche share. The fact that both firms are family businesses that maintain long-term relationships with their employees is one of the similarities in company culture that facilitates communication. Both companies are used to being consultants as well as manufacturers. Loctite® provides its customers with hightech solutions and individual support. Porsche actually started as an engineering consulting company and has ­retained that feature until today. One of the interesting features of what the American ­author Bruce Sterling calls the “silent revolution in ­adhesive ­chemistry” is the fact that adhesive technology doesn’t ­always receive a great deal of attention in academia. Groundbreaking research and innovative ideas are ­often a result of business needs and take place in companies rather than natural science faculties. Henkel is trying to remedy this situation, however, and is making its long years of experience and extensive know-how available to ­universities in a number of cooperation projects. As a ­professional partner to young engineers and a product ­supplier to their racing teams, Loctite® has been part of “Formula Student” for several years. Threadlocker Loctite® 2700: Health & Safety counts Flange sealant Loctite® 574: fast cure speed Threadlocker Loctite® 270: high strength for extreme loads Threadlocker Loctite® 243: vibration resistant, removable assembly High-speed engineering for professionals The Bahrain story of the German driver René Rast makes abundantly clear how crucial good engineering and ­maintenance is to succeeding in the Supercup. Ten minutes before the start of the race, René Rast wanted to drive out of the garage, but suddenly there was a loud crack! His chances of making it to the grid in time didn’t look good. One of the two drive shafts had gone. Seven mechanics instantly swarmed the car and managed to do the impossible: within only 8 ­minutes and 23 seconds they had replaced the shaft, using threadlocker Loctite® 243 to ­secure the six bolts holding the shaft to the gearbox. “The change of the drive shaft was done in just over eight minutes”, says ­engineer Frank Funke, proud of his team Veltins MRS Racing, in an interview with racecam.de. “I owed this result to my boys”, a grateful Rast said after the race. He came in second, beaten only by Bleekemolen. Richard Westbrooke, Supercup winner in 2005 and 2006, achieved a third place on his comeback to the Supercup. at work | no. 2/09 6 | Reliability Report 3 Hard work Siberia, minus 50 °C. A giant truck rumbles along the gravel of the coal mines, with the powerful determination of an angry rhino. The giant used in the Siberian mines was manufactured in Scotland, just like its twin brother doing hard work in copper mines under the blazing Mexican sun. The factory in Scotland at work | no. 2/09 Ready for delivery A wheel as big as a man Wheel suspension of a 100 ton truck Reliability Report 3 These trucks, used for heavy mining work in some of the world's most treacherous areas, are produced by the American company Terex®. Vehicles exposed to the full force of extreme climates and loads rely on high-end technology in combination with solid engineering to get the job done. This is where Loctite® products make an impact, and the two companies have a long standing business relationship. 22 bolts are secured with Loctite® 648 at work | no. 2/09 | 7 8 | Reliability Report 3 Terex® markets more than 50 brands covering a broad range of ­equipment for the construction, infrastructure, quarrying, recycling, surface mining, ­shipping, transportation, refining, utility and maintenance industries. Henkel had the chance to send a film crew to the Terex® plant in Glasgow, ­Scotland to see Loctite® products in action. The enormous power the Terex® machines wield requires the reliability that Loctite® adhesives and sealants can ensure. Locating studs – locked with high strength anaerobic compound Loctite® 648 – allow easy and fast ­fixturing of the differential, a crucial construction part exposed to strong forces. The rigid flanges of the differential housing are sealed with Loctite® 518. ­Besides instant seal, Loctite® 518 guarantees the reliable long-term performance ­because there is no gasket relaxation, and correct clamp load is maintained throughout the life of the assembly. This is a perfect example of how ­Loctite® products provide optimisation in production. A wheel as big as a man Inspiring strong feelings How do you measure a company’s appeal? Is it the level of brand ­awareness? The market position? Customer loyalty? There is another way of doing it, by asking a simple question: whose ­products will inspire more excitement in a conversation amongst school children? ­Applying that measure, even Porsche and Ferrari will have hard time ­competing with Terex®. The American firm is the manufacturer of the biggest digger and the strongest crane in the world. The list of awe-inspiring products from Terex® doesn’t stop here. At the Scottish location, gigantic coal-mining trucks and other heavy duty applications are assembled. To get an idea of how big these trucks really are, just picture a wheel that is as tall as a grown man. Terex® produces seven different models of these trucks, with ­loading ­capacities up to 100 tons. Attention to detail and emphasis on good craftsmanship are the ­ ttributes that Terex® and Loctite® engineers share. “Jackie is ­always a just a phone call away,” says Steven Macholecki, a supervisor at the ­Scottish Terex® plant in a video documenting the use of Loctite® in ­production. Jackie is Jackie Marshall, the Loctite® sales engineer ­responsible for Terex® in Glasgow. Marshall spends at least one day a week at the plant in Glasgow, and the ­cooperation with the Terex® engineers seems to be working well for both ­parties. “I’m involved in finding adhesive and sealant solutions for new ­designs, but I’m also there when they encounter maintenance problems,” he explains. at work | no. 2/09 Reliability Report 3 | Long-life, reliable gasketing solution Globally, Terex® is a well-known name when it comes to equipment for the construction, infrastructure, quarrying, recycling, surface mining, shipping, transportation, ­refining, utility, and maintenance industries. Among its portfolio is an impressive range of heavy duty vehicles including ­cranes, dumpers, excavators, digger derricks and rollers, as well as both rigid and articulated trucks. “The company has built a reputation for providing high ­quality products that do their jobs with efficiency,” ­explains David Brown, Technical Support Engineer at the Terex® base in Motherwell, Scotland. “The differential flange must be sealed in a way to ensure long-term reliability by ­eliminating leak paths.” Terex® already used a number of Loctite® products on its ­vehicles for a variety of applications, so it was natural to call in the local Henkel sales engineer, Jackie Marshall, to recommend a solution. “The answer was to use a liquid gasketing ­product,” ­states David. “It was recommended that ­Loctite® 518 was ­trialled for the purpose – and this provided the solution we were seeking.” vehicle differentials, but also on gearbox, axle and engine flanges such as timing covers. It provides an ­instant seal against low pressures, fills gaps up to 0.25 mm, and is ­effective at temperatures ranging from -55 °C to +150 °C. Reliability at work The size of the flange surface meant that application ­techniques needed to be taken into consideration. “We are talking about a two-inch wide film on a three-foot ­diameter flange,” declares David. “With such an area to cover, ­normal ­application methods – such as the use of a ­standard ­dispensing gun – were not really suitable. Again, ­Henkel through its Loctite® products was able to help.” Customer: Terex®, Scotland That help came in the form of the Loctite® Trax Roller. This is a roller (similar to the one used for painting) that is ­attached to a dispensing gun, allowing the gasket ­material to be ­applied quickly with a very even film over the whole area.

Once the domain of bearded men wearing Birkenstock ­sandals, they have now arrived in corporate boardrooms all over the world. Sustainability has become a buzz word in the ­business community. What exactly does sustainability mean to you, though? That is the question that Henkel Product Manager Erik ­Edelmann and his team asked their industrial customers. “For most customers it is rather difficult to clearly define sustainability. The term generally encompasses energy and climate, materials and waste, water consumption, health and safety, as well as social progress. However, the ­primary focus is clearly on occupational health and safety and ­environmental responsibility,” says Edelmann. • No safety phrases • No declarable CMRs A clean sheet This was not an entirely new challenge for Henkel, as the company has always placed great importance on non-­ hazardous substances and minimal eco-toxicity in the more than one hundred years of its history. With the new ­threadlockers Loctite® 2400 and Loctite® 2700, Henkel has broken new ground in occupational health and safety. The medium strength threadlockers Loctite® 2400 and the high strength threadlocker Loctite® 2700 are a leap ­forward, because they both have a “white” MSDS ­(Material Safety Data Sheet). “A white MSDS means that according to the tough ­regulations of (EC) No. 1907/2006 - ISO 11014-1 both threadlockers do not carry any hazard symbols, risk or safety phrases. In addition, they do not contain any ­declarable CMRs (Carcinogenic, Mutagenic and ­Reproductive ­toxins),” explains Edelmann and continues: “You will be surprised to see that your ordinary ­dishwashing agent or all-­purpose cleaner carries more hazard symbols than these ­industrial products.” RD&E Insights The evolution of new adhesives David Condron Senior Chemist, Product Development Europe, Dublin, Ireland at work | no. 2/09 Never sacrifice performance As usual, the Henkel specialists in the Dublin ­Technology centre were working together very closely with their ­customers during the development process. “In the case of Loctite® 2400 and Loctite® 2700, we were ­collaborating with two large customers in France,” says Edelmann. His professional background is in chemical engineering, a ­training which greatly facilitated the communication with leading developer David Condron in Dublin. “The ­customers took a very cautious approach and insisted that not even the decomposition products should be ­hazardous,” says Condron. Not willing to sacrifice performance, Condron and his ­colleagues worked for more than a year on the project and finally made it happen: they developed products that retained the customary high Loctite® performance with a “white” health and safety bill. “We were lucky to have the chance to cooperate with highly sophisticated and demanding customers,” says Edelmann. RD&E Insights The medical officers in France took a ­personal ­interest in the project and gave direct feedback on the ­various ­prototypes. By meeting the customer’s needs, ­Loctite® ­engineers set a new standard in the realm of ­industrial threadlocking. “I have to say that we are proud of this achievement and the fact that we were able to ­reaffirm Henkel’s position as a technological industry leader,” ­Condron stated at the end of the interview. Because safety matters: Loctite® threadlockers with a “white” health and safety bill Quality and responsibility have always been important issues at Henkel. Continuously striving to improve the Health & Safety of its ­products, the company breaks new ground with the medium strength ­threadlocker Loctite® 2400 and high strength threadlocker Loctite® 2700. These two products retain the same outstanding level of performance customers have come to trust, with the essential added benefit of enhanced occupational health and safety: • Loctite® 2400 and Loctite® 2700 require no hazard symbols, no risk phrases and no ­safety phrases on Material Safety Data Sheet complying with the tough EU regulations • They do not contain any declarable CMRs (Carcinogenic, Mutagenic and ­Reproductive toxins) • They do not require any entries in sections 2, 3, 15 and 16 of the MSDS according to (EC) No. 1907/2006 - ISO 11014-1 No compromise on performance Medium strength threadlocker Loctite® 2400 is fluorescent blue with a viscosity of 3000 mPa·s and a shear strength on steel of 9 N/mm2. The high strength Loctite® 2700 is fluorescent green, has a viscosity of 500 mPa·s and a shear strength of 18 N/mm2. Once cured, both products offer excellent resistance against most industrial chemicals. They achieve good thermal resistance, withstanding continuous operating temperatures up to 150 °C. at work | no. 2/09 | 11 12 | Integrated Solutions A perfect combination What do cars, aeroplanes, syringes, shoes, trucks, water taps, arrows from ­ancient Mongolia, spaceships and tunnel boring machines have in common? The answer is: the use of a ubiquitous, yet rarely noticed technology- adhesive ­engineering. Even though the use of glue can be traced back to the Neanderthals, the last 30 years have seen an enormous increase in its reliability as well as in industrial ­adhesive ­applications. Stefan Frisch Application Technologist ­Henkel Engineering Adhesive at work | no. 2/09 Hermann Handwerker Manager European Technical Service, Henkel Munich According to Stefan Frisch and Hermann Handwerker from Henkel in Munich, this is not only a fact normally ignored by the layman; even engineers and academics don’t give adhesives the credit they deserve. “University courses only touch briefly on ­adhesives, one of the “youngest” joining technologies, if they include them at all,” says Frisch, an application technologist. “A lot of the research and the ­innovation results from companies like Henkel who are trying to meet customer needs," adds Handwerker. Integrated Solutions Handwerker, who holds a PhD in chemistry, continues: “After university, I didn’t even think about the adhesive ­industry as a possible employer. And I think it’s the same for most engineers, too; using adhesives is somehow seen as ­second best, something to be avoided,” he explains. This is of course completely unjustified, according to Frisch and Handwerker, who almost seem like missionaries for the adhesive cause during this lunch-time interview, their zeal hardly allowing them to finish their meals. Standard or tailor made? They might have a point, as a look around the Henkel test centre in Munich demonstrates. Just ­behind the entrance there is a showcase displaying a ­variety of items ­produced with the use of ­adhesives: Loudspeakers, syringes and infusion ­bottles to name just a few. The centre in ­Munich is one of the places where Loctite® specialists ­conduct the ­research that Handwerker and Frisch referred to during the ­interview. Frisch points to a differential gear in one of the rooms and ­explains: “This is a project we’ve been ­working on for more than a year. A customer from the ­automotive industry wanted us to find an ­adhesive solution for putting ­together the parts of this ­differential.” This is one of the ­benefits of working for ­Henkel: ­Finding and ­testing ­solutions is a service that Henkel offers as a ­support to customers in their ­development ­process. ­ onditions. Applying the products prevents ­fretting and c ­corrosion, minimises costly breakdowns and extends ­service life. Appropriate dispensing equipment is ­available for ­manual as well as other application jobs in the ­workshop. And should there be problems: the local sales engineer is just a phone call away. Product applications can be found in a wide range of ­industries. Special packages have been developed for ­applications on pump, centrifuge, power plant, shaft and, last but not least, water treatment which by all accounts will be one of the growth industries of the 21st century. Is there further room for development when it comes to the use of industrial adhesives? Silly question: “Of course there is,” says Handwerker. “This is a relatively new ­technology and we have just scratched the surface of what’s ­possible.” This sentence almost exactly echoes a statement made by his colleague featured in the first issue of this ­magazine about the Tear Down Centre. There, an interdisciplinary team of specialists looks at each component of a finished product to see whether the value of the product can be ­enhanced or the cost of manufacturing can be reduced. All these efforts help to spread the word about the power of ­adhesives and sealants. But finding or creating the right product is only the first step; the second step is ­applying and ­dispensing the product in the right manner. This is the area that ­Frisch specialises in. “We offer a large ­variety of standard ­equipment, both for manual and ­automatic ­dispensing,” he says. Again, the Loctite® ­engineers work on a problem until they have come up with a solution that will stand the final test of continuous use on an ­assembly line or in a factory workshop. “If no combination of ­standard ­equipment will do, we have a team responsible for ­designing tailor-made solutions,” Frisch continues. One of the advantages of being the market leader for such a long time is the wealth of experience and know-how the team in Munich has accumulated. The customer gets the right product and the appropriate dispensing equipment all in one, which leads to very user friendly solutions. The omnipresent customer need to cut costs is very much on the minds of the Loctite® crew in Munich. ­Loctite® ­adhesives offer benefits not only in manufacturing, but also for maintenance and repair. Loctite® ­engineers have ­developed solutions that emphasise prevention rather than repair. A good example for this strategy is the ­gearbox and shaft package they have assembled: a range of more than 20 products developed to perform ­under ­extreme at work | no. 2/09 | 13 14 | Trend Report Maintenance − the invisible power of development Since humans first began developing tools, there has always been a need to m ­ aintain them. The careful maintenance of an economic production ­p rocess was often a ­necessity for survival, especially in times of scarce and valuable commodities. The road to implementing modern industrial maintenance was a long one. Given the ­d evelopments ahead of us, we are still at the beginning of that road. at work | no. 2/09 Trend Report The history of maintenance is also the history of culture and an allegory to the industry's conception and ­philosophy. ­Effective and efficient maintenance is, more than ever, ­vital for development, particularly in times of financial ­crises and reduced turnover, increasing costs for energy, ­commodities and labour. Today, Maintenance, Repair and Overhaul (MRO) costs more than € 1,500 bn per year in the EU alone, and more than € 7,000 bn worldwide. Over 50 million jobs are ­directly related to MRO, and 150 million jobs are ­indirectly ­related. ­However, requirements for MRO are ­increasing and, ­especially in times of financial ­crisis and ­reduced ­budgets, are difficult to meet. Laws are ­tightening the scope to ­respond to these requirements, as well as ­meeting ­customers’ demands, incorporating new ­technologies, and considering economic and ecologic necessities. However, ­modern industry would not be able to work ­efficiently ­without up-to-the-minute and innovative methods of ­maintaining tools and equipment. The early years of industry − maintenance by ­accident In the early stages of industrial development, breakdowns were commonplace due to the means of production and, consequently, down-times were high. The symbol of early maintenance was “the man with the oil can”. And, beside this basic service, one simply had to ­repair the damage as it occurred. There were no ­monitoring systems available at that time, and the ­analysis of ­probability of ­failure was in the early developmental stages. The transformation of failure based on preventive ­maintenance began with traffic engineering; initially from the railways, and later with aviation technology. The ­immediate danger to human life and the difficulties encountered on the way to carry out maintenance work were the driving forces in the development of preventive maintenance. Prevention is better than a cure − preventive ­maintenance The reorientation of preventive maintenance in the ­industry did not start in Europe or the US, but in ­post-war ­Japan. In an exemplary manner, industrial production was ­transformed after World War II. The simple concept was to follow manufacturers’ recommendations about the ­controlled care and maintenance of machines and ­devices, which was not so usual in the 1950s. It was part of the Japanese Kaizen philosophy, which means (in this context) “continuous improvement toward the better”. Looking into the crystal ball − predictive ­maintenance By the 1960s, increasing competitive pressure led to a steady improvement and continuity of production plants. Consequently, the reliability of equipment and the ­probability of error intervals became predictable, ­depending on load and production time. This knowledge led to the ­increasing quality standards of used materials and ­manufacturing processes. Predictive maintenance was not able to ­foresee ­occurrences caused by incidence or ­failure but this ­approach led to distinct statistical knowledge, which was reused by modern technology and software. at work | no. 2/09 | 15 | Trend Report Itaipú: the largest hydro­ electric power plant on earth. Some of the 20 ­tubes ­leading water to the turbines at Itaipú dam on ­Paraná ­river, located on the border between Brazil and Paraguay. Putting the pieces together − total productive maintenance At the start of the 1970s, globalised competition required a further increase in production efficiency to reduce costs. The Japanese Institute of Plant Engineering merged US maintenance concepts to create a new standard. The core of the new concept was “autonomous maintenance”. The key to its success was the knowledge and experience of the facility operators. Based on this new philosophy, maintenance became part of the entire production and development process. ­Prerequisite was to improve all aspects of production and maintenance; from the planning and development of ­systems to their care and beyond. The unique ­element of this ­concept was “Zero Goals”, which means “no ­unplanned downtimes caused by preventable failures” and, as a final objective, ensures that Total Productive Maintenance (TPM) is a continuous improvement process. at work | no. 2/09 Safety, health and ­environment Education and training TPM in office Initial flow control Quality maintenance Planned maintenance Equipment and process ­improvement TPM Autonomous maintenance 16 Optimising the I/0-ratio − risk-based smart ­maintenance The goal of Risk-based Smart Maintenance is to ­monitor the conditions of equipment to calculate the probability of a breakdown and to perform maintenance when it is most cost-effective. Therefore, the comprehensive and sensitive Condition Monitoring (CM) of the load on the parts of an installation is essential to gain the data for risk calculation. Modern CM systems meet the highest demands on sensors, data ­collection, forwarding and automatic processing, analysis and diagnosis, as well as plant-specific knowledge. Risk-based Smart Maintenance also offers the ­greatest ­potential for cost savings. The life of critical machine ­elements can be almost fully exploited while, at the same time, necessary maintenance activities can be scheduled in coordination with the production plan. The challenges of this strategy can be seen in: • The search for appropriate sampling and sensors • Finding the relevant parameters (state variables) for the damage to the components of interest • The signal analysis and pattern recognition • The enormous flood of data • Data-analysis and models for risk assessment Behind the scenes − maintenance technologies of the future Smart Monitoring is only possible as a result of advances in technology in the fields of mechanics, acoustics, ­systems theory, electronics and computer science. Sensors in thin film technology, which can be placed directly onto the Trend Report structure to be monitored, allow a precise data on critical zones. It also enables Smart Monitoring, which balances activities and controls measures. Downtime in a highly-effective plant can cost enormous amounts each minute. A modern power plant, for ­example, produces up to 1,500 MW from each turbine. Large power plants, such as Itaipú in South America, have 20 lines. Measured by international energy spot market prices, each minute of downtime costs the plant roughly €1,500. Far more ­error-prone in production is the automotive industry. Here a line has clock rates of less than a minute. So each minute of downtime could exceed the total amount of one car’s gross profit. RFID – smart objects everywhere Smart tagging by RFID technology is another approach to realise cost-effective maintenance for complex ­industrial machines and plants. RFID enables the implementation of a smart object from planning to construction, ­assembling, ­maintenance, disassembly and reassembly. Maintenance will be much easier with self-monitoring smart objects, which are able to store their data history, to communicate with a CMD, to stimulate necessary steps ­automatically, and to lead service teams to the area where the work is ­required. In this context, the concept of ubiquitous ­computing will lead to a new approach in dealing with the growing complexity of plants and technology. Mobile maintenance communication services In order to avoid downtime, the 24/7 availability of all ­required service parts has to be guaranteed. ­Successful and fast operating logistics is a key factor of efficient ­maintenance. Requirement and delivery times will be ­reduced to a minimum through mobile communication ­systems. In ­connection with RFID technology, ­specifications of work pieces, ­maintenance instructions, technical details and construction plans of even the most complex systems will be available at any time and place. The chemistry of maintenance For a long time, maintenance has been seen primarily as a matter of material technique, handcraft and physics. With the development of complex and sensitive plants, ­chemistry has increasingly found its way into processes. Today, a maintenance team not using numerous ­chemical aids such as lubricants, metalworking fluids, protecting sprays or silicone speciality products is inconceivable. Improving maintenance is imperative to ­cost-effective ­production. Given to a standard industrial net profit ­ratio, a reduction of 1 % in maintenance costs may have the same ­effect a 33 % increase in turnover. Even in times of lower turnover, the demand to reduce the cost of labour (which covers 60 % of MRO spendings) will meet ­maintenance as well as all other aspects of production. Therefore, the smart replacement of procedures, such as the ­substitution of welding by bonding technologies, will be able to ­contribute an important share to this goal.

Currently, some US universities are ­developing Knowledge-based Augmented Reality for ­Maintenance ­Assistance. These systems are tentatively ­using a ­head-mounted display to explain maintenance ­information, construction plans or sensor data. New materials for a new world In 1912, the Krupp company developed a new kind of steel (a mixture of iron, chromium and nickel) with ­excellent strength and durability against corrosion. At that time, it was a significant step toward reliability. Today, new ­materials with ­outstanding properties are available to enable new ­applications. Plastics, composites and carbon fibre have been available for some time now and are widely used in numerous industries, from tunnelling to aviation. Along with these new ­materials, new maintenance requirements will be sent to the suppliers of MRO. Currently, self-healing products with the ability to ­partially repair damages are in development, but are not in ­commercial use. Another approach to future maintenance are the amazing capabilities of nano-tech materials with a high capability of increasing the stability of equipment by improved components and processes. From the outset, the goal of maintenance has been to ­increase profit by reducing losses in productivity. Plants and production of the future will have to be far more ­complex than they are today. Highly sophisticated ­maintenance technologies are part of the solution.

This at work | no. 2/09 | 17 18 | Reliability Report 4 The poetry of added value A slight, but unmistakable scent of vanilla pervades the hallway, and the attention of the visitor is captured by the nostalgic beauty of some antique Italian motorcycles decorating the room. What seems like the entrance to an exclusive spa or a fancy hang-out for motorcycle enthusiasts actually leads to a showroom for water taps and showerheads. But if you associate water taps and shower heads with the ­a ppropriate aisle in the DIY store, you need to think again.

Since its foundation in 1876, Henkel’s mission statement has remained “to produce products to make life easier, ­better and more beautiful”. Beauty, not just the beauty of products, also plays an extremely important role in the Gessi philosophy, which sometimes reads like an artistic manifesto and dazzles with sentences like these: “The core value of the business system is beauty. Beauty does not ­refer exclusively to the aesthetic value of the product since it’s a dimension that pervades every aspect of the business.” The average DIY store customer will probably be astonished to learn that a manufacturer of water taps believes that “the true added value of a brand is its poetry content and its respect for the world”. ­Therefore, the manufacturer hasem barked on a mission to create artistic ­consumer goods, goods that are meant to “induce a reflection on the morality of ­objects”. Manufacturing beauty Gessi, however, doesn’t only talk the talk; at the plant in Serravalle Sesia, it walks the walk: “We don’t want to compete with low price ­manufacturers in China. We deliver the highest quality, both in design and functionality and it’s working very well for us,” explains Andrea Renna, the Quality Assurance Director. This is no exaggeration: the company’s turnover grew by a stunning 23 % in 2007.

The Rettangolo Color tap lines feature the ­trademark minimalist elegance, relying on geometrical shapes: in this case an open rectangle. When water passes through, a temperature-­ sensitive LED lights up in different colours – blue, purple, or red – ­according to the water temperature. Loctite® has been a partner to Gessi from the very beginning, and ­Loctite® threadlockers play an important role in the manufacturing ­process of a large number of Gessi products. “We use Loctite® ­products for every screw that needs to be secured and watertight,” explains Andrea Renna. Be it the extraordinary square showerheads or the huge water taps for industrial kitchens, Loctite® always plays a vital part in ensuring the ­durability of the fittings. Elegant production The plant in Serravalle Sesia, which is just across the road from the ­showroom, is another reflection of the company’s emphasis on beauty and design. The production facility resembles a giant lab styled in the company colours – orange and black. Every worker wears a shirt or a sweater with the company logo. The preferred means of ­transportation within the plant are bicycles. These are, of course, black and orange and bear the company name as well as the name of the user or the ­department. Reliability Report 4 Assembly of water taps for hand washbasins with Loctite® 638 Rettangolo Color tap is ready for use Assembly of water taps for kitchen sinks with Loctite® 243 Quadro High Tech is ready for use Even though Gessi sells its products to business and private ­customers all over the world, the entire production process takes place in the ­Serravalle ­Sesia plant. Producing in a high-wage region like northern ­Italy is not seen as a liability, but as an integral part of a company ­philosophy which emphasises quality and a high standard of human relationships. Modern times haven’t stopped at Gessi’s doorstep, however. The ­factory, which is clean and orderly to the point of sterility, belying all stereotypical perception of Italian chaos and laissez faire, employs robots and other advanced production technology wherever possible. The yellow robots in their metal cages with their graceless, yet effective, movements ­feature prominently, especially at the beginning of the assembly line. “We automate where we can,” says Renna. “But due to the ­sophistication of our products, a lot of work has to be done by hand and this will ­continue to be the case.” While showing us through the plant, Renna points to red Loctite® bottles that can be seen on top of many of the work benches ­inside the facility. Gessi handles, soap dispensers or ­mirrors all rely on the performance of Loctite® 638. Creative solutions However, the collaboration between Henkel and Gessi transcends the usual ­supplier-customer relationship. As companies whose ­success ­depends heavily on a continuous process of innovation and the ­ability to respond quickly to global market demands, Gessi and Henkel have ­entered a relationship that can be best described as a form of ­partnership. Quality Assurance Director Renna recalls the case of a soap ­dispenser that Gessi sold to Russia. “Because of the temperature ­differences, the regular glue we used gave out and broke the glass. We were able to solve the issue by making use of the flexibility built into ­certain ­Loctite® products,” says Renna. | Andrea Renna, Quality Assurance ­Director, Gessi Spa “Gessi is the leader in bathroom and kitchen sanitary ware and ­accessories. As of today, we are a worldwide reference for the “Made in Italy” seal as a company whose products are featured in the most exclusive hotels, in the best wellness spas and on the most expensive yachts. Although it is a designer product, it is, above all, a quality product. Quality of production, quality of the working environment, quality in the way we produce our appliances and the way we choose our ­suppliers. Loctite® is a partner which fully meets our philosophy.” “If there is a challenge where we can assist, we take care of it ­immediately,” says Massimigliano Moneta, Loctite’s Technical Sales ­Consultant ­responsible for Gessi. Loctite® maintains a laboratory in ­Milan and the response comes within a matter of days. “Up to now, we have always been able to find a ­solution, normally by pointing out an ­alternative use for one of the products from our range,” says Moneta. Even if that shouldn’t be the case at some point in the future, there is ­always the European ­Technology ­Centre in Dublin ready to take on the task of finding a creative adhesive for a ­creative customer. at work | no. 2/09 21 22 | Handy Hints The knowledge toolbox Whether you are designing a new product, or looking to keep existing machines running efficiently, Loctite ® can help.
