Abstract
Curable resin compositions comprising a blend of an epoxy resin, a polyurethane resin which comprises the reaction product of (A) a polyisocyanate, (B) a polyester resin and (C) a dihydric alcohol, and a standard epoxy resin curing agent. These resinous compositions, when cured, retain excellent resilience and exhibit outstanding adhesion. They are especially useful for bonding vinyl materials.
