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.
