D.E.R 642U Epoxy resin Dow Chemical Epoxy Resins >> Bisphenol A based Coatings >> Powder Coatings General Industrial /Maintenance Powder coating D.E.R.* 642U solid epoxy resin is a novolac modified high molecular weight solid reaction product of liquid epoxy resin and bisphenol-A. D.E.R. 642U solid epoxy resin is a novolac modified resin with an average functionality of approximately 2.6. It is designed for powder coating applications. The resin is mainly used in industrial powder coatings in combination with D.E.R. 663U epoxy resin, D.E.R. 664U epoxy resin or D.E.R. 667 epoxy resin cured with a phenolic hardener. Formulations using D.E.R 642U epoxy resin provide excellent corrosion and chemical resistance combined with good mechanical properties. Typical examples of applications include pipe coatings and internal drum linings. Novolac modified high molecular weight solid reaction product of liquid epoxy resin and bisphenol-A. Used for industrial powder coating applications in combination with other epoxy resin cured with a phenolic hardener. Provides very good corrosion and chemical resistance, and good mechanical properties. Suits for pipe coatings and internal drum linings.
