SOLVENT-BASED RELEASE COATING-FORMING ORGANOPOLYSILOXANE COMPOSITION AND RELEASE FILM OR SHEET

摘要

To provide a solvent-based release coating-forming organopolysiloxane composition exhibiting excellent release properties. The organopolysiloxane composition comprising (A) organopolysiloxane having two alkenyl groups, (B) organohydrogenpolysiloxane having at least three silicon-bonded hydrogen atoms bonded in side-chain position on the molecular chain, (C) straight-chain organohydrogenpolysiloxane having a viscosity at 25°C of 2.5 to 2,000 mPas and silicon-bonded hydrogen at both molecular chain terminals, (D) a platinum-type catalyst, and (E) organic solvent and optionally (F) a photopolymerization initiator.
