D.E.R. 672U solid epoxy resin is a novolac modified resin with an average functionality of approximately 2.6. It combines the high reactivity of D.E.N. 438 epoxy novolac resin with the high softening point range of D.E.R. 667 solid epoxy resin. These properties are of particular interest in powder coating applications where through the addition of 10-50 % by weight of D.E.R. 672U solid epoxy resin, calculated on standard resin, extra edge coverage is obtained. When used in combination with D.E.R. 664U solid epoxy resin, cured with a phenolic hardener such as D.E.H. 82 curing agent, final coatings exhibit excellent mechanical properties combined with good corrosion and chemical resistance. 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 powder coating applications. Offers high reactivity and high softening point range. Gives mechanical properties and good corrosion and chemical resistance. Suits for pipe coatings and internal drum linings.
