Patent ID: 7273911

Claim:
An addition-crosslinking silicone composition comprising at least one organopolysiloxane (A) bearing minimally two aliphatically unsaturated groups, at least one organohydropolysiloxane (B), and at least one hydrosilylation catalyst, further comprising at least two adhesion promoters, a first adhesion promoter which is a multi-nuclear aryl compound (C) bearing at least one aliphatically unsaturated group or substituent having at least one aliphatically unsaturated group, and a second adhesion promoter (D) which is an organopolysiloxane bearing at least one terminal silicon-bonded hydrogen, and having, as silicon-bonded moieties other than terminal silicon-bonded hydrogen, moieties selected from the group consisting of hydroxyl and monovalent, optionally halogen substituted C 1-20 hydrocarbon radicals free of aliphatically unsaturated groups, wherein individual carbon atoms may be replaced by O, N, S, or P atoms.
