Abstract
There is disclosed a fluorosilicone composition which, when cured onto a substrate such as paper, provides a surface which readily releases such tacky materials as silicone pressure-sensitive adhesive, said composition comprising PA1 (A) 100 parts by weight of an organopolysiloxane that contains in each molecule at least 1 fluorine-containing organic group and at least 2 alkenyl groups; PA1 (B) 0.1 to 40 parts by weight of an organohydrogenpolysiloxane that contains at least 2 silicon-bonded hydrogen atoms in each molecule; PA1 (C) 0.01 to 20 parts by weight of an organopolysiloxane that contains in each molecule at least 1 fluorine-containing organic group, with the proviso that said organopolysiloxane (C) contains neither alkenyl groups nor silicon-bonded hydrogen groups; and PA1 (D) a catalytic amount of a hydrosilylation catalyst.
