Abstract
A method of curing certain organopolysiloxane compositions by a combination of heat and exposure to ultraviolet radiation or electron beam provides the ability to use lower temperatures than heat cures alone and shorter cure times than ultraviolet radiation or electron beam alone. The organopolysiloxane compositions are addition-curable and are made up of alkenyl-containing organopolysiloxane, organohydrogensiloxane, a platinum catalyst, an addition-reaction inhibitor selected from alkynol, 3-methyl-3-pentene-1-yne, 3,5-dimethyl-3-hexene-1-yne, methylvinylsiloxane cyclics, benzotriazole, and mixtures thereof, and a photosensitizer.
