Title:
CURABLE SILICONE COMPOSITION, RELEASE COATING AGENT COMPRISING SAID COMPOSITION, RELEASE FILM OBTAINED USING SAID RELEASE COATING AGENT, AND LAYERED PRODUCT INCLUDING SAID RELEASE FILM
Document Type and Number:
WIPO Patent Application WO/2020/138417
Kind Code:
A1
Abstract:
Provided is a curable silicone composition for a release agent by which a release film having a low peeling force from a silicone pressure-sensitive adhesive can be formed even as a thin layer, and by which, after the release film is peeled, the adhesive strength of the silicone pressure-sensitive adhesive to another substrate is reduced as little as possible. Also provided are: a release film and a layered product for which the peeling force of a silicone pressure-sensitive adhesive is low; and a method for producing the layered product. This curable silicone composition contains: (A) a fluorine-containing organopolysiloxane mixture obtained by mixing a component (A1) and a component (A2) at a mass ratio of 1/99-99/1, with (A1) a fluoro(poly)ether-modified organopolysiloxane which has at least two alkenyl groups per molecule and has a fluoro(poly)ether-containing organic group, and (A2) a fluoroalkyl group-containing organopolysiloxane which has at least two alkenyl groups per molecule and has a fluoroalkyl group represented by the formula C4F9-CH2CH2-; (B) an organopolysiloxane having at least three silicon atom-bonded hydrogen atoms per molecule; (C) a hydrosilylation reaction catalyst; and (D) an organic solvent.
