D.E.R.® 663U

D.E.R.® 663U Solid Epoxy Resin is a low molecular weight solid reaction product of epichlorohydrin and bisphenol A. D.E.R.® 663U Solid Epoxy Resin is a low molecular weight, solid epoxy resin developed mainly for use in powder coatings. It can be incorporated in both pure epoxy and epoxy/polyester systems where the relationship between its melt viscosity and softening point properties ensures the production of homogeneous powders with good gloss, excellent flexibility and smoothness, and good storage stability. D.E.R.®. 663U Resin can also be used in epoxy ester applications, for example, in industrial or automotive coatings.
