Abstract:
1. A curable ambient cure high-solids coating composition comprising: (a) an epoxy resin; (b) an amphiphilic block copolymer containing at least one epoxy resin miscible block segment and at least one epoxy resin immiscible block segment; wherein the immiscible block segment comprises at least one polyether structure; such that upon curing the epoxy resin composition, the toughness based on elongation at break of the resulting cured epoxy resin composition modified with said amphiphilic block copolymer is increased as compared to a cured epoxy resin composition without being modified with said amphiphilic block copolymer; and (c) a sufficient amount of a nitrogen-containing curing agent to cure the coating composition at ambient temperature of less than 60° C.
