Patent ID: 8258502

Claim:
A composition prepared by mixing components comprising: (I) an alkenyl functional, phenyl-containing polyorganosiloxane having an average compositional formula given as R 1 a R 2 b SiO (4-a-b)/2 where R 1 is an alkenyl group having 2 to 12 carbon atoms, each R 2 is independently a methyl group or a phenyl group, at least 30 mol % of R 2 are phenyl groups, a and b are positive numbers having values such that: a+b=1 to 2.2 and a/(a+b)=0.001 to 0.05; (II) a hydrogendiorganosiloxy terminated oligodiphenylsiloxane having a molecular formula given as HR 3 2 SiO(SiPh 2 O) x SiR 3 2 H where Ph represents a phenyl group, each R 3 is independently a methyl group or a phenyl group, x is an integer from 2 to 8, and x has an average value of 2 to 4; and (III) a hydrosilylation catalyst.
