Two component curable epoxy resin composition having a long pot life

A two-part curable composition, the first part comprising (a) a resin mixture comprising 60-95% of compounds having epoxy function groups and 5-40% of compounds having acrylate or methacrylate ester groups; and (b) .5-5% based on resin mixture weight of a free radical photoinitiator, and the second...

Zusammenfassung:	A two-part curable composition, the first part comprising (a) a resin mixture comprising 60-95% of compounds having epoxy function groups and 5-40% of compounds having acrylate or methacrylate ester groups; and (b) .5-5% based on resin mixture weight of a free radical photoinitiator, and the second part comprising an amine component selected from polyoxyalkylene polyamines, tertiary amines and mixtures thereof. The compositions which are characterized by UV surface cures in less than a minute, and long pot life, have particular utility in electronics applications.
