<p>PURPOSE:To prepare the title composition which can be easily released from a sticking material, and has stable properties with time, by adding an organo-polysiloxane modified with an alcohol or a polyether, to a specific silicone composition for forming a release film. CONSTITUTION:The objective composition is prepared by mixing (A) a release- film-forming composition composed of (a) an organo-polysiloxane containing two or more Si-bonded vinyl groups in a molecule and having a viscosity of >=100 cps at 25 deg.C, (b) an organo-hydrogen polysiloxane containing two or more SiH groups in a molecule, and (c) a metal catalyst for addition reaction, e.g. chloroplatinic acid, etc., and (B) 1-40 parts by weight, based on 100 parts of (a)+(b), of (d) an alcohol-modified organo-polysiloxane or (e) a polyether-modified organopolysiloxane.</p> |
