SATURATED EPOXY RESIN COMPOSITIONS EXHIBITING IMPROVED GLOSS RETENTION Abstract of the Disclosure The preparation of solid saturated epoxy resin compositions, which when cured with conventional epoxy curing agents yield coatings exhibiting improved weatherability, i.e., better gloss retention and better chalk resistance, are described. The solid saturated epoxy resins are prepared by reacting liquid or semisolid saturated epoxy resins with a heterocyclic amine, such as 5,5-dimethylhydantoin, preferably in the presence of a suitable catalyst.
