Silicone composition and cured product
摘要：
A silicone composition is provided comprising (A) an organopolysiloxane of resin structure consisting of R1SiO1.5, R22SiO, and R3aR4bSiO(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 R1SiO1.5, R22SiO, and R3cHdSiO(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.
