Abstract
Adhesion promoting compositions for bonding a layer of organic polymer to a layer of organosiloxane elastomer during curing of the elastomer by a platinum group metal-catalyzed hydrosilation reaction comprise (a) a copolymer containing repeating units derived from at least one ethylenically unsaturated organic compound and at least one silane containing an ethylenically unsaturated organic group and at least two silicon-bonded hydrolyzable groups per molecule, and (b) an organohydrogensiloxane containing an average of at least three silicon-bonded hydrogen atoms per molecule. If the adhesion promoting composition is to be used with an elastomer prepared by curing an organosiloxane elastomer at temperatures below about 80 degrees C., the adhesion promoting composition includes an alkyl orthosilicate and an organotitanium compound.
