PURPOSE:To obtain a composition giving a film having excellent curing, mold release and slip characteristics, exposure resistance and peeling force continuing for a long period of time, by blending organopolysiloxane with organic silicone compound, a specific organopolysiloxane and platinum group catalyst. CONSTITUTION:(A) 100 pts.wt. unsaturated group-containing organopolysiloxane having at least two unsaturated group bound to silicone atoms in a molecule is mixed with (B) 0.1-10 pts.wt. organic silicone compound having at least two hydrogen atoms bound to silicone atoms in a molecule, (C) 0.1-50 pts.wt. one end Si-H bond stopping organopolysiloxane expressed by the formula (plural R<1> are monfunctional organic groups without aliphatic unsaturated bonding; R<2>, R<3> and R<4> are organic groups same as R<1> with a proviso that one of the three is H; n is 1-100) and (D) platinum group catalyst. |
