Surface Treatment
• Next generation surface treatment for aluminum and steel with improved cost and environmental profile
• Improve corrosion protection on e.g. lamp housings for exterior lighting
• Support your cost and sustainability goals:
- Less process steps
- Low temperatures
- No sludge with heavy metals
Low Pressure Moulding – General and Transparent
• Increase luminaire quality and life span: protecting electronic components from humidity and impact
• Optimise your manufacturing process: overmoulded parts are ready for the next process step in less than 1 minute
– no curing time required
• Directly overmould PCBs and in many cases elimate need for additional housing for components
• Improve your sustainability footprint: low pressure moulding adhesives are made of renewable raw materials
Dispensing Equipment
For some jobs it is sufficient to dispense product directly from the bottle or tube onto the surfaces to be
joined. In other cases, however, more precise and automated dispensing is required. In addition to the
standard equipment available, Henkel can design and build equipment based upon customers requirements
to provide unique application solutions.

Street and Car Park Lighting
Lamp housings are used for exterior street lighting and car parks and must
withstand exposure to the elements, hot/cold temperature extremes, dust, dirt,
and road vibration. Using Henkel e.g. bonding and sealing, potting, and surface
treatment solutions in lamp housing design and manufacturing, ensures long life
and trouble-free operation.

Did You Know?
The average life of an LED can be as long as 50,000
hours. Compare this to the 1,000-hour life of an
incandescent bulb and the 8,000-hour life for compact
fluorescents (CFLs).

LEDs project light forward, while most other light
sources emit light in all directions. This makes LEDs
optimal for spotlights and floodlights.

Consumer and Residential Lighting
New and exciting designs are becoming even more important to differentiate your
luminarie in the consumer and residential market. The use of LEDs for residential
and consumer lighting is growing as incandescent become obsolete and concerns
remain over the safety and disposal risk of CFLs.
Henkel bonding, thermal management, and potting products can help manufacturers
realise their design ambitions and build a better, more reliable and potentially
lower-cost luminaire.

Architectural Lighting
Safety is paramount when it comes to swimming pool, deck and outdoor lighting.
Henkel e.g. surface treatment, potting, and low pressure moulding solutions can
help achieve a safe, reliable, watertight enclosure to ensure the integrity of underwater and weather-exposed lighting components.

Advertisement and Logo Lighting
Illuminated advertisement and logos are an important element of the visual
identity of your business. When used outside, they must withstand exposure to
these elements while maintaining the high quality appearance of your design. In
addition, the requirements of corporate design rules must be met, as for example
displaying correct company colour tones.

The standard unit of measurement that defines the output or brightness of an LED is called a lumen. The more
lumens an LED has, the brighter the light.

Hand-Held Applicators
Loctite Hand-Held Applicators are ergonomically
designed for hand delivery of Loctite adhesives and
fluids directly from their original package. Whether
pneumatic or manual, each item is designed for easy,
clean, hand-held dispensing of fluids, to reduce waste
and operator contact. The selection of a Loctite HandHeld Applicator is based on the product type, package
size, and process requirements. Available for:
• 1 Component Cartridges
• 2 Component Cartridges

Light Curing Equipment
Four major effects must be taken into consideration
when designing a successful light cure application:
emission spectrum of the cure system, light intensity,
transmission properties of substrate and required
cure characteristics. As a manufacturer of both the
chemistry and the curing equipment, Henkel knows
how to match light cure adhesives to the correct
dispensing and curing system.
• Flood Cure Systems
• Spot Cure Systems
• Meters & Accessories

Henkel Adhesives Satisfy Stringent Criteria
for Use with Cree® LEDs
Volatile organic compounds (VOCs) may be found in various chemical products such as cleaners, lubricants, solvents, thermal
compounds as well as adhesives and sealants. When enclosed together with LEDs during luminaire assembly, incompatible
VOCs may degrade the light output performance, change the colour points and reduce the life span of LEDs.
Incompatibility comes in varying degrees: some chemical materials are critical when in direct contact with LEDs but are fine
when enclosed without being in contact with the LED (indirect contact - also referred to as proximity). Some materials, such
as adhesives and sealants, may be critical during the curing process, but less so when fully cured.
Cree® has defined a testing methodology to evaluate chemical compatibility. Many Henkel products meet the requirements
set forth by Cree® and we are committed to continue systematically testing our products. This will help you select the right
adhesive and sealant for your application and be assured that incompatibility will not become an issue for you.
Chemical Compatibility to LEDs VOC Entry and Failure Mechanism
Silicone Lens
1. LEDs are typically protected by an ultra clear silicone lens
LED Chip
VOC
Enclosure, e.g.
luminaire housing
2. When enclosed during luminaire assembly, some volatile
organic compounds (VOCs) may diffuse into silicone lens
3. Heat and photon energy discolor VOCs and reduce lumen
output or may cause failure of LED
