ABSTRACT:
Epoxy resin compositions catalyzed with combinations of diaryliodonium salts of complex halogenides and copper salt catalyst activators are rendered stable at room temperature, but fully activatable at elevated temperatures by including an effective amount of a carboxyl terminated copolymer of butadiene and acrylonitrile, a hydroxy terminated copolymer of butadiene and acrylonitrile or a mixture thereof.
