Silicone composition and cured product

摘要

A silicone composition is provided comprising (A) an organopolysiloxane of resin structure consisting of R¹SiO_1.5, R²₂SiO, and R³_aR⁴_bSiO_(4-a-b)/2 units, wherein R¹, R², and R³ are methyl, ethyl, propyl, cyclohexyl or phenyl, R⁴ is vinyl or allyl, a is 0, 1 or 2, b is 1 or 2, a+b is 2 or 3, the number of recurring R²₂SiO units being 10 to 300, (B) an organohydrogenpolysiloxane of resin structure consisting of R¹SiO_1.5, R²₂SiO, and R³_cH_dSiO_(4-c-d)/2 units, wherein R¹, R², and R³ are as defined above, c is 0, 1 or 2, d is 1 or 2, c+d is 2 or 3, the number of recurring R²₂SiO units being 10 to 300, and (C) a platinum catalyst. The silicone composition cures into a product exhibiting flexibility and minimized surface tack, and can be effectively molded on the existing molding machines.
