Beckopox EH 659w/50WA Polyamidoamine Solutia Crosslinking / Coupling / Curing Agents >> Amines /Amides >> amidoamine Epoxy (EP) BECKOPOX Epoxy resin dispersions and water-soluble hardeners The BECKOPOX family of epoxy resin dispersions and water-soluble hardeners can be used as primers, sealers, curing compounds and topcoats in a wide range of applications in the protection of structures and equipment. What makes BECKOPOX particularly attractive is its ability to deliver exceptional performance and value with a low volatile organic compound (VOC) formulation (< 250 grams per liter of VOC). Uses The BECKOPOX proprietary dispersant system for liquid resins produces a small particle size dispersion (less than one micron on average) that does not migrate from the paint film. This results in exceptional stability, convenient viscosity and excellent performance features that make BECKOPOX particularly useful in the following applications: Industrial Maintenance Coatings BECKOPOX industrial maintenance coating formulations provide high gloss finishes that meet or exceed the performance of solvent-borne epoxies in gloss, adhesion, chemical resistance, abrasion resistance and impact strength. BECKOPOX based topcoat and primer starting formulations provide 2000 hours of salt fog and humidity resistance in applications such as general industrial maintenance auto refinish and shop primers. In direct-to-metal topcoat formulations, 2 mil BECKOPOX formulation provides over 1000 hours of salt fog and humidity resistance on phosphated steel. Drying and curing times are betterthan expected from other epoxy dispersions. Institutional Maintenance/Architectural Coatings BECKOPOX epoxy dispersions, when used with carboxy functional acrylic emulsions, produce institutional maintenance and high-performance architectural coatings that provide superior gloss and performance characteristics when compared to other dispersion systems. In applications such as schools and hospitals, its low odor, low VOC, fast drying time and quick development of physical properties offer easy application and allow the painted area to be back in service with minimum down time. Concrete Primers and Topcoats Concrete and masonry primers and topcoats formulated with BECKOPOX epoxy resins and curing agents provide floors, structures and facades with exceptional resistance to corrosive chemicals, staining and abrasion. BECKOPOX primers can be applied directly to wet concrete (usually just four hours after pouring), with no loss of adhesion — resulting in significant time, labor and material savings. The prime coat can usually be followed within one hour with a water-based topcoat. In addition, BECKOPOX formulations can be applied at temperatures near freezing, while most competitive products require minimum temperatures of 50 degrees F. The water-based BECKOPOX coatings offer excellent adhesion, fast drying, high coverage rate, smooth flow and leveling and excellent lapping. Coatings formulated with BECKOPOX resins have been found to be easier to manufacture in true production conditions. Performance Advantages The low VOC BECKOPOX formulations have several high performance characteristics: High gloss Excellent color acceptance Excellent in-can stability (pot life of up to nine hours) Low temperature application (down to freezing temperatures) Excellent chemical and physical properties Fast drying and curing Easy, economical application Reproducible, trouble free manufacture and handling of epoxy dispersion Low odor BECKOPOX EH 659w/50WA Polyamidoamine 50 % in water (50WA) Low reactive hardener for water reducible coatings on mineral and metallic substrates. Partner for high reactive hardeners. Beckopox EH 659w is used together with solid epoxy resin dispersions or emulsified liquid resins (Beckopox EP 384w, EP 122w, EP 147w). This low reactive hardener is mainly used together with reactive hardeners like Beckopox EH 623w, to improve pigment wetting, levelling and penetration into porous concrete substrates. In metal coatings additions to other hardeners can improve adhesion and corrosion resistance. If pigment dispersion is carried out in the hardener component, the concentration should not be below 30 %. It is also important that the mill base temperature does not exceed 40 °C. The main application field for formulations based on Beckopox EH 659w is concrete coating. It is essential to apply the paint within the time stated for pot life because the end of the pot life can not be detected from an increase in viscosity or gellation. Polyamidoamine in water.
