Process for forming an epoxy-acrylate coating

Abstract

This invention relates to a heat curable composition comprising (a) a liquid, ethylenically unsaturated monomer, oligomer or prepolymer of the formula: ##STR1## wherein R is H or CH.sub.3, R.sub.1 is an organic moiety and n is at least 2, (b) an epoxy resin containing at least two ##STR2## groups, and (c) a thermal initiator member of the group consisting of (1) a substituted or unsubstituted diaryliodonium salt in combination with a free radical initiator, (2) a BF.sub.3 adduct, (3) a BF.sub.3 adduct in combination with a free radical initiator, and (4) dicyandiamide in combination with a free radical initiator. The system is stable at ordinary temperatures, but on heating the thermal initiator catalyzes the curing of the acrylate and the epoxy resin.
