CURABLE ORGANOPOLYSILOXANE COMPOSITION, SHEET-LIKE ARTICLE HAVING A CURED LAYER FORMED FROM SAID COMPOSITION, AND LAMINATE

摘要

A solvent-type curable organopolysiloxane composition comprising (A) at least one type of gum-like or liquid organopolysiloxane having a viscosity of not less than 20 mPA·s, a content of the vinyl(CH2=CH-) part of higher alkenyl groups being in a range of 2.0 to 5.0% by mass; (B) an organopolysiloxane having a viscosity of not less than 1,000,000 mPa·s, a content of the vinyl(CH2=CH-) part of alkenyl groups being less than 0.1% by mass; (C) an organohydrogenpolysiloxane; (D) a hydrosilylation reaction catalyst; and (E) an organic solvent. In such a composition, a mass ratio of the component (A) to the component (B) is in a range of 2/8 to 8/2.
