SOLVENTLESS CURED RELEASE COATING-FORMING ORGANOPOLYSILOXANE COMPOSITION AND SHEET-FORM SUBSTRATE HAVING A CURED RELEASE COATING |
摘要 |
<p>A solventless cured release coating-forming organopolysiloxane composition having a viscosity at 25°C of 50 to 2,000 mPa·s comprising (A) 100 weight parts of an alkenyl-functional diorganopolysiloxane that has a viscosity of 25 to 1,000 mPa·s; (B) 0.5 to 15 weight parts of a diorganopolysiloxane that has a viscosity of at least 10,000 mPa-s and that has an aliphatically unsaturated group content of no more than 0.1 mole %; (C) 0.5 to 5 weight parts of a branched organopolysiloxane that has more than one SiO4/2 unit and that is a polymer product provided by an equilibration polymerization between a branched organosiloxane oligomer represented by the average siloxane unit formula (1) ( S i O 4 / 2 ) ( R aR b 2 S i O 1 / 2 ) X (1 ) and a diorganosiloxane oligomer; (D) a specific amount of an organohydrogenpolysiloxane that has a viscosity of 1 to 1,000 mPa·s; and (E) a hydrosilylation reaction catalyst in a catalytic quantity.</p> |
