Document Type and Number:
WIPO Patent Application WO/2022/138349
Kind Code:
A1
Abstract:
[Problem] To provide a curable silicone composition for a release agent that can form a release film in which, even when the film is thin, the release force is small from a silicone adhesive, particularly from a silicone adhesive having a low storage modulus at a low temperature. Further, to provide: a release film that has a low release force and that has superior smoothness of an adhesive layer surface after release; a laminate; and a method for producing said laminate. [Solution] A curable silicone composition comprising: (A) a mixture of two or more types of fluoroalkyl group-containing organopolysiloxanes which are not compatible with each other, which each include a fluoroalkyl group and an alkenyl group, and in which the contained amounts of fluoroalkyl groups are different from each other; (B) an organohydrogen polysiloxane; (C) an organopolysiloxane that has a fluorine atom-containing organic group and that does not include a hydrosilylation reaction-causing group; (D) a catalyst for hydrosilylation reaction; and (E) an organic solvent. A use of a release film or the like provided with a cured product of said curable silicone composition.
