Abstract
Organopolysiloxane compositions which cure by the addition reaction of silicon-bonded lower alkenyl radicals with silicon-bonded hydrogen atoms and which exhibit improved adhesion to a variety of substrates. The compositions comprise an adhesion promoting mixture comprising an epoxy-functional compound, a compound having at least one hydroxy group and in the same molecule at least one substituent selected from a group consisting of silicon hydride, alkenyl, and acryl, and an aluminum compound or zirconium compound. Compression set of the cured organopolysiloxane compositions is not significantly effected by the adhesion promoting mixture.
