PURPOSE:The titled composition providing improved releasability and slipperiness, capable of being applied to paper, etc., containing no organic solvent, obtained by blending a specific organopolysiloxane with specific amounts of an organohydrogen polysiloxane and a platinium compound. CONSTITUTION:(A) 100pts.wt. substantially straight-chain organopolysiloxane which contains two or more vinyl groups bonded to Si atoms in one molecule, has 0.5-10mol based on total organic groups of vinyl group and 50-10,000cps viscosity and shown by the formula I (R is methyl, etc.; m and n are >=1) is blended with (B) 0.5-40pts.wt. organopolysiloxane which contains a hydroxyl group (formula II) bonded to Si atom at the end of the molecular chain, has >=100,000cps viscosity and a substantially straight-chain structure, (C) 0.5-50pts. wt. organohydrogen polysiloxane containing >= two or more hydrogen atoms bonded to Si atom in one molecule and, (D) a catalytic amount of a platinum compound. The composition has 50-10,000cps viscosity. |
