Process for forming a coat

摘要

According to the present invention, a coat is formed by applying a coating composition comprising an epoxy resin obtained by a bisphenol represented by the formula: wherein R1 and R2 represent a hydrogen atom or an alkyl group containing from 1 to 3 carbon atoms and a curing agent, to a substrate; and thereafter contactings the resulting coat with a liquid such as warm water or hot water in a one stage or multistage process. The thus formed coat is excellent in properties shch as heat resistance, particularly erosion resistance adhesive properties and resistance to leaching of organic constituents contained in the coat exposed to hot water.
