Abstract

Substrates are coated with relatively high molecular weight epoxy resin coatings by applying to a substrate a mixture comprising PA1 (A) a relatively low molecular weight epoxy resin such as the diglycidyl ether of bisphenol A, PA1 (B) a phenolic hydroxyl-containing compound such as bisphenol A and PA1 (C) a catalyst for effecting a reaction between (A) and (B), and subjecting the coated substrate to a temperature of 120.degree. to 300.degree. C.
