Title
(EN) SILICONE RELEASE AGENT COMPOSITION, RELEASE SHEET AND RELEASE FILM
(JA) シリコーン剥離剤組成物、剥離紙及び剥離フィルム
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a release agent composition showing extremely low peeling force to a silicone adhesive and giving excellent residual adhesive force to the adhesive after peeling.

SOLUTION: The release agent composition comprises: (A) a linear or branched organopolysiloxane containing no fluorine-containing groups, which has at least two alkenyl groups and at least one aryl group in one molecule and has specific ranges of a percentage of the number of the alkenyl groups and of a percentage of the number of the aryl groups with respect to the number of groups bonded to a Si atom, by 50 to 99.9 pts.mass; (B) a linear or branched organopolysiloxane, which has at least one alkenyl group and a fluorine-containing group in one molecule and a percentage of 3% to 50% of the total of the fluorine-containing groups with respect to the total of groups bonded to a Si atom, by 50 to 0.1 pts.mass; (C) an organohydrogen polysiloxane containing no fluorine-containing groups, which has a specific range of a ratio of (number of SiH)/(number of alkenyl groups) and has at least three H atoms bonded to a Si atom in one molecule; and (D) a platinum group metal-based catalyst in a catalytic amount.
