ABSTRACT:
A composition comprising a vinylchloride/olefin copolymer and a small amount of an epoxy resin is provided. The epoxy resin reacts with residual surfactants in the copolymer on heating. Coatings of the composition have satisfactory hot water resistance. Coatings prepared from the copolymer without epoxy resin have inconsistant performance as to hot water resistance with a substantial tendency toward pitting as shown by "blushing."
