ABSTRACT:
A heat vulcanizable silicone rubber composition has been developed which bonds cohesively to many substrates with either vinyl specific or non-vinyl specific organic peroxide vulcanizing agents when vulcanized in contact with the clean substrate. A method has been developed which uses an adhesion additive composition consisting essentially of polydiorganosiloxane gum, filler, ethylpolysilicate, and a specific acryloxyalkylsilane. The method combines the adhesion additive with silicone rubber stock and organic peroxide vulcanizing agent to yield the heat vulcanizable silicone rubber composition which bonds to substrates.
