Patent ID: 7494694

Claim:
An adhesive silicone elastomer composition which can be crosslinked under hot conditions by polyaddition (hydrosilylation), this composition being of the type of those comprising: α/ at least one PolyOrganoSiloxane (POS) carrying ethylenic and/or acetylenic unsaturation(s) {POS comprising ≡Si-[unsaturation] units}; β/ at least one polyorganosiloxane (POS) carrying ≡Si—H units; γ/ a catalytic combination comprising: γ.1 at least one metal catalyst γ.2 and at least one crosslinking inhibitor; δ/ a filler; ε/ at least one adhesion promoter; ρ/ at least one POS resin; λ/ at least one agent for stability toward heat; φ/ optionally at least one other functional additive; said composition being a single-component composition wherein the crosslinking inhibitor γ.2 is selected from the group of compounds of following formula (I) or (II): in which: R is identical or different, represents a linear, branched or cyclic alkylene radical or a substituted or unsubstituted arylene radical, in particular: i. a linear or branched alkylene radical having in particular from 2 to 30 carbon atoms (C), ii. an alkylene radical comprising one or more rings, in particular 1 or 2, it being possible for a ring to have in particular from 4 to 14 C, or iii. an arylene or alkylarylene radical comprising one or more fused or nonfused aromatic rings, in particular 1 or 2 rings, it being possible for a ring to comprise from 4 to 14 C, optionally substituted by 1 or more, in particular from 1 to 2, linear or branched alkylene(s) having in particular from 1 to 12 C and wherein: R1, R2, R3, R4, R1′, R2′ and R3′, which are identical or different represent a linear alkyl radical or a substituted aryl radical in particular; i. a linear or branched alkyl radical having in particular from 2 to 30 carbon atoms(c). ii. an alkyl radical comprising one or more rings, in particular 1 or 2, it being possible for a ring to have in particular from 4 to 14 C, or iii. an aryl or alkylarylene radical comprising one or more fused or nonfused aromatic rings, in particular 1 or 2 rings, it being possible for ring to comprise from 4 to 14 C, optionally substituted by 1 or more, in particular from 1 to 2, linear or branched alkyl(s) having in particular from 1 to 12 C wherein the inhibitor γ.2 corresponds to either of the following formulae (III) or (IV): in which the R 5 radicals, which are identical or different, are linear or branched alkyls having in particular from 1 to 12 C.
