Abstract:
An adhesive silicone composition comprising:(A) 100 parts by weight of a diorganopolysiloxane containing at least two aliphatic unsaturated monovalent hydrocarbon radicals in a molecule, represented by the following average compositional formula (1):R.sup.1.sub.a SiO.sub.(4-a)/2 ( 1)whereineach R.sup.1, which may be the same or different, represents a substituted or unsubstituted monovalent hydrocarbon radicals, anda is a positive number in the range: 1.18<a<2.2, said diorganopolysiloxane having a viscosity of 10 to 10,000,000 centipoise at 25.degree. C.;(B) 0 to 50 parts by weight of an organohydrogenpolysiloxane containing at least two hydrogen atoms each attached to a silicon atom in a molecule, represented by the following average compositional formula (2):R.sup.2.sub.b H.sub.c SiO.sub.(4-b-c)/2 (2)whereineach R.sup.2, which may be the same or different, represents a substituted or unsubstituted monovalent hydrocarbon radicals, andb and c are positive numbers in the range: 0.78<b.ltoreq.2, 0.005<c.ltoreq.0.6, and 0.785<b+c.ltoreq.2.6;(C) 0.01 to 30 parts by weight of an organic silicon compound having at least one phenyl skeleton, at least one nitrogen atom, and at least one hydrogen atom directly attached to a silicon atom in a molecule, wherein said nitrogen atom is contained as a nitrogenous radical which is selected from the group consisting of --NR--, --NR--CO--, --NR--CO--O--, --NR--CO--NR--, --NR--CN--NR--, --NR--CH.sub.2 --CH(R)--CO--O--, --NR--CH.sub.2 --CH(OR)--, --NR--CH(CH.sub.2 OR)--CH--, and mixtures thereof,whereinR is hydrogen or a substituted or unsubstituted monovalent hydrocarbon radical of 1 to 6 carbon atoms; and(D) a catalytic amount of a platinum catalyst.
