SETAQUA ECO5000 is APEO free and has dual crosslinking mechanism. Due to its unique design, this binder does not require any coalescing solvents for film formation at temperatures down to 5 °C while maintaining excellent block ® resistance properties. Innovative technology of SETAQUA ECO5000 enables formulating high gloss paints with no or minimum added wet-edge extenders which lead to coatings with minimal VOC content which comply with Green Star Rating requirements. The addition of a small amount of wet edge extenders results in excellent overall appearance, gloss and flow characteristics while maintaining the VOC levels below 50 grams per litre where according to APAS document D181, the acceptable average VOC level for interior high gloss coatings is equal or less than 75 grams per litre1.

Careful selection of these components is required; as selecting the wrong additive or the wrong combination of additives will impair the performance of SETAQUA® ECO5000. Formulation advice for SETAQUA® ECO5000 is given below. Please be aware that some additives may require dilution to avoid the possibility of aggregation. Note: The information provided is only a recommendation and the appropriate concentration of coalescent and additives must be determined by the formulator. ► Dispersing Agents Successful formulations based on SETAQUA® ECO5000 have been formulated using Disperbyk 199 and/or Orotan 731. Concentrations of these additives vary depending on the type and concentration of pigment being dispersed. ► Defoamers SETAQUA® ECO5000 is compatible with a wide range of polysiloxane defoamers such as BYK 022 and BYK 093. ► Surfactants Formulations based on SETAQUA® ECO5000 using APEO free phosphate ester surfactants such as Dextrol OC-6025 have been shown to improve tinter acceptance properties. SETAQUA® ECO5000 is also compatible with many APEO free and APEO surfactants including Triton CF-10 and Teric N9. ► Thickeners Good results have been found with SETAQUA® ECO5000 when thickened with the non-ionic associative thickeners such as Acrysol RM2020, Aquaflow NHS-350 and Aquaflow XLS-525. Paints based on SETAQUA® ECO5000 would also benefit from true Thixotropes such as BYK 420 in achieving acceptable anti settling properties without negatively impacting the levelling properties. ► Titanium Dioxide Tronox CR-828 has been found to give good results with SETAQUA® ECO5000. ► Extenders Omyacarb and talc extenders both give good gloss reduction in SETAQUA® ECO5000. ► pH and pH adjustment The self cross-linking mechanism in SETAQUA® ECO5000 is not influenced by pH and high performance coatings based on this resin can be formulated between a pH of 8 to 8.5. pH can be adjusted by secondary amines such as pHLEX 410 or AMP95. ► Open time and wet edge extension The wet edge of SETAQUA® ECO5000 can be extended with propylene glycol. It is also compatible with non-VOC wet-edge extenders such as Byketol PC. Technical Bulletin Setaqua ECO5000 Version 1.0 May 2012 Page 4 of 10 Comparative Data The performance of SETAQUA® ECO5000 is highlighted in the following starting point formulations. It is important to note that the full potential performance of SETAQUA® ECO5000 is achieved only when product is used in a complete undercoat-topcoat system on MDF or timber. ► White High Gloss Enamel Based on SETAQUA® ECO5000 Formulation Number: EP2312007 COMPONENT Add to dispersion vessel: Propylene glycol Water 1 Orotan 731 DP 25% * Byk 022 AMP95 2 Disponil NG 4060 2 Disponil A 1080 3 Tronox CR828 1 Acrysol RM2020 kg/1000L 45.0 9.0 10.4 1.0 1.0 2.0 1.0 250.0 15.0 …Grind on a high speed mixer for 15 minutes at 20m/sec tip speed… Water * BYK 420 10.0 0.8 ® SETAQUA ECO5000 * BYK 093 4 Dextrol OC-6025 Water * 740.0 2.0 20.0 116.0 * BYK 381 4 Aquaflow XLS530 2.0 2.0 Total 1227.20 Raw Materials 1 *Available from Nuplex Available from Dow 2 3 Available from Cognis Available from Tronox 4 Available from Nuplex Specialty Specific Gravity VOC (APAS) g/L % Non-volatile content (by weight) % Non-volatile content(by volume) % PVC pH Gloss (20°/60° after 7 Days) KU viscosity ICI Cone and Plate Viscosity Technical Bulletin Setaqua ECO5000 Version 1.0 May 2012 1.23 48.0 47.3 35.4 18.0 8.5 72/89 90-95 KU 1.3-1.5 P Page 5 of 10 Comparative Data ► White Primer Undercoat Based on SETAQUA® ECO5000 Formulation Number: EP2312009 COMPONENT Add to dispersion vessel: Propylene glycol Water 1 Orotan 731 DP 25% * BYK 022 AMP95 2 Disponil NG 4060 2 Disponil A 1080 3 Tronox CR828 Talc T30A kg/1000L 45.0 130.0 20 1.20 1.0 2.0 1.0 250.0 220.0 …Grind on a high speed mixer for 15 minutes at 20m/sec tip speed… Acrysol RM2020 Water * BYK 420 ® SETAQUA ECO5000 * BYK 093 Water 25.0 32.0 1.6 * * BYK 381 4 Aquaflow XLS530 Total 588.0 2.0 40.0 3.6 2.0 1360.8 Raw Materials 1 *Available from Nuplex Available from Dow 2 3 Available from Cognis Available from Tronox 4 Available from Nuplex Specialty Specific Gravity VOC (APAS) g/L % Non-volatile content (by weight) % Non-volatile content(by volume) % PVC pH Gloss (60° after 7 Days) Technical Bulletin Setaqua ECO5000 Version 1.0 May 2012 1.36 48.0 54.3 37.9 38.5 8.5 7 Page 6 of 10 Comparative Data Above high gloss starting point formulation (EP2312007) based on SETAQUA® ECO5000 has been compared to three commercially available white waterborne acrylic gloss trim enamels. Testing focussed on features required of waterborne enamels, when compared to their solventborne counterparts, such as high 20 degree gloss levels, open time and depth of image. ► 20 and 60 Degree Gloss on Glass 150µm wet films were drawn down on glass and left to cure for 24 hours at 25°C and 50% RH before being measured for gloss. Samples were then re-measured after seven days to check for any further loss of gloss. SETAQUA® ECO5000 was the only paint that showed 20 degree gloss levels of more than 70% which brings the performance of product closer to that of Solventborne enamels. 60 Degree Gloss 95 90 Gloss % 85 80 75 70 65 60 Setaqua ECO5000 Commercial Product I Commercial Product II Commercial Product III 24hr 7 Day 20 Degree Gloss 75 70 Gloss % 65 60 55 50 45 40 Setaqua ECO5000 Commercial Product I Commercial Product II Commercial Product III 24 hr Technical Bulletin Setaqua ECO5000 Version 1.0 May 2012 7 Day Page 7 of 10 Comparative Data ► 20 and 60 Degree Gloss on MDF For this test a topcoat-undercoat system based on SETAQUA® ECO5000 was tested against a commercial waterborne acrylic undercoat-topcoat system and also a commercial long oil alkyd based topcoat on a waterbased acrylic undercoat. The primer undercoat used for SETAQUA® ECO5000 system is based on starting point formulation EP2312009. For this test the undercoat and two layers of top coat were applied at a spread rate of 16 sqm per litre.

It is important to note that due to better holdout of the undercoat based on SETAQUA® ECO5000, final system gloss is much higher than that of waterborne acrylic enamel. ► Block Resistance 150µm wet films were drawn down and left to cure for 24 hours and one week at 25°C. Samples were judged as per ASTM 4946-89(2003) where 10 is no block and 0 is complete failure. A force of 40 g/cm2 was applied to the coatings for 30 minutes at 50°C.

The test was performed on 100µm wet films that were cured for one week at 25°C. Films were judged immediately after the stains were removed and scored on a scale from 0 to 5, in which 0 means total marking of the film and 5 means no mark was left on the film.

They were then left for a prescribed time. The damaged area was then repaired by brushing 10 horizontal and 10 vertical strokes over the damaged area. Observations were made one minute before the time where a cross is still visible in the dried film of the coating after last brush stroke. For meaningful comparison of open time, results have been discussed as a factor of paint VOC. Studying the commercial paints, VOCs can vary between 45 and 75 grams per litre. Hence paints based on SETAQUA® ECO5000 were prepared at close to zero, 48 and 75 grams per litre. As can be seen in the following graph, paints based on SETAQUA® ECO5000 lead to 30 to 50 percent improvement in open time, compared to standard commercial acrylic based enamels at equal VOC levels.

Storage ® SETAQUA ECO5000 should not be stored at temperatures below 5ºC or above 35ºC. Avoid exposure to direct sunshine. Under normal storage conditions (5°C - 35°C, away from extremes) sealed, unopened containers of this material would have a shelf life of 12 months from the date of manufacture. If it is stored for longer than 12 months, it is recommended that the product is rechecked for suitability in the intended application. SETAQUA® ECO5000 is protected from attack by microorganisms for at least 6 months. Additional preservative should be added to guard against microbial attack when the dispersion is being stored for longer periods of time and tank hygiene measures must be adopted.
