Beckopox EM 443/57XMIBK Epoxy/phenolic resin precondensate Solutia Epoxide (EP) >> Phenol & Cresol (Novolacs) 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 EM 443/57XMIBK Epoxy/phenolic resin precondensate 57 % in xylene/methyl isobutyl ketone (57XMIBK) (containing also 4 % methoxypropyl acetate) In combination with adduct-hardeners for cold-curing highly chemical-resistant two component primers and coatings. Beckopox EM 443 is an epoxy/phenolic resin precondensate especially suitable for the formulation of cold-curing primers and coatings with very good resistance to chemicals. Notable features are the good adhesion properties on both metals and mineral substrates. The resistance of the fully hardened paint films to chemicals is excellent, especially the resistance to alkaline solutions and acids. In addition these films have good resistance to various solvents. - Applications as interior coatings of containers, silos or tanks in the chemical or textile industry. - Coatings in the food industry, e.g. in breweries, wine vaults and canning factories. - Installations in nuclear power plants that need to be capable of decontamination. - Corrosion-protection systems in road and bridge constructions, wastewater treatment plants and waterworks. Beckopox EM 443 is combined with amine adducts such as Beckopox EH 631. Through-hardening generally takes place at room temperature. In this case coatings can be subjeckt to stress after about 7 days. The time taken for through-hardening can be reduced by the application of elevated temperatures, e.g. 24 hours at 50 °C. This improves resistance to chemicals at the same time. The recommended method of obtaining optimum properties is to use multiple coatings. Usually one coat of primer and two topcoats are sufficient, although a further one or two topcoats are necessary if the coatings are likely to be in contact with highly aggressive chemicals.
