D.E.R. 338-X90 Epoxy Resin Solution is a semi-solid bisphenol-A epoxy resin dissolved in xylene. It is an intermediate epoxy equivalent weight epoxy resin used mainly in adhesives and protective coatings, or as a modifier for other epoxy resins to improve impact strength, extensibility, and adhesion.
The excellent resistance and physical properties have established D.E.R. 338-X90 as a major raw material for epoxy coal tar combinations and higher solids content marine coatings. D.E.R. 338-X90 can be used to modify performance as well as handling properties of liquid epoxy resin, such as D.E.R. 331 and epoxy novolac-type resins, such as D.E.N. 431 and D.E.N. 438.
A wide variety of curing agents is available to cure this resin at ambient conditions. Most frequently used curing agents are aliphatic polyamines, polyamides, and modified versions of these. If anhydride or catalytic curing agents are employed, elevated temperature and long-post cures are required to develop full end properties.
