Patent ID: 7553915

Claim:
A silicone composition comprising (A) an organopolysiloxane of resin structure consisting of R 1 SiO 1.5 units, R 2 2 SiO units, and R 3 a R 4 b SiO (4−a−b)/2 units, wherein R 1 , R 2 , and R 3 each are a methyl, ethyl, propyl, cyclohexyl or phenyl radical, R 4 is a vinyl or allyl radical, a is 0, 1 or 2, b is 1 or 2, the sum a+b is 2 or 3, the number of recurring R 2 2 SiO units being 10 to 300, (B) an organohydrogenpolysiloxane of resin structure consisting of R 1 SiO 1.5 units, R 2 2 SiO units, and R 3 c H d SiO (4−c−d)/2 units, wherein R 1 , R 2 , and R 3 are as defined above, c is 0, 1 or 2, d is 1 or 2, the sum c+d is 2 or 3, the number of recurring R 2 2 SiO units being 10 to 300, in such an amount that a molar ratio of silicon-bonded hydrogen atoms in component (B) to vinyl or allyl radicals in component (A) is from 0.1 to 4.0, and (C) an effective amount of a platinum group catalyst.
