Abstract: Provided is a curable silicone composition for a release agent which can form a release film having a silicone adhesive with a low release force even when thin and which does not reduce the adhesive strength of the silicone adhesive to other substrates upon releasing the release film. A release film and laminate are also provided. The curable silicone composition comprises: (A) a fluorine-containing organopolysiloxane mixture obtained by mixing the following components (A1) and (A2) at a mass ratio of 1/99 to 45/55: (A1) a fluoro(poly)ether modified organopolysiloxane having at least two alkenyl groups per molecule along with a fluoro(poly)ether-containing organic group; (A2) a fluoroalkyl group-containing organopolysiloxane having at least two alkenyl groups per molecule along with a fluoroalkyl group having 1 to 12 carbon atoms; (B) an organopolysiloxane having at least three silicon atom-bonded hydrogen atoms per molecule; (C) a hydrosilylation reaction catalyst; and (D) an organic solvent.

Abstract: Provided is a curable silicone composition for a release agent which can form a release film having a silicone adhesive with a low release force even when thin and which does not reduce the adhesive strength of the silicone adhesive to other substrates upon releasing the release film. Also provided is a release film, laminate, and method of manufacture. The curable silicone composition comprises: (A) a fluorine-containing organopolysiloxane mixture obtained by mixing the following components (A1) and (A2) at a mass ratio of 1/99 to 99/1; (A1) a fluoro(poly)ether modified organopolysiloxane having at least two alkenyl groups per molecule along with a fluoro(poly)ether-containing organic group; (A2) a fluoroalkyl group-containing organopolysiloxane having at least two alkenyl groups per molecule along with a fluoroalkyl group represented by 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.
