Abstract
Organosiloxane compositions curable by a platinum-catalyzed hydrosilation reaction contain as the adhesion promoter a silane comprising an silicon-bonded alkenyl radical containing at least five carbon atoms and at least one alkoxy group. The silane or a hydrolysis-condensation product thereof is optionally used in combination with a catalyst that promotes reaction of the silane with groups present on the surface of the substrate to which bonding is desired.
