Abstract
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 dihydroxy phenol such as resorcinol in the presence of a suitable catalyst.
