SILICONE COMPOSITION FOR FORMING A DIFFERENTIAL RELEASE AGENT FOR USE WITH SILICONE ADHESIVE AND DOUBLE SIDE DIFFERENTIAL RELEASE PAPER OR FILM

摘要

Provided is a silicon composition for forming a differential release agent for a silicon adhesive, capable of stably supplying a cured thin film which can control peeling force in an intermediate-high peeling force range with respect to the silicon adhesive. The composition for forming a differential release agent for a silicon adhesive comprises (A) organopolysiloxane, (B) organohydrogen polysiloxane having at least three hydrogen elements coupled to silica elements in one molecule and (C) a platinum group metal catalyst. The organoposilxane has at least two alkenyl groups coupled to silica elements in one molecule, respectively has at least one of (a) a fluoroalkyl group and (b) a fluoro polyether group as two types of fluorine containing substituents coupled to silica elements, wherein the content of (b) the fluoro polyether group with respect to (a) the fluoroalkyl group and (b) the fluoro polyether group is 1-99 mol%.
