Document Type and Number:
WIPO Patent Application WO/2022/236796
Kind Code:
A1
Abstract:
Provided is a fluorosilicone release coating composition comprising: (A) a linear organopolysiloxane having at least two alkenyl groups and at least one fluoroalkyl group per molecule, and not having a silicon atom-bonded hydrogen atom: (B) a branched organopolysiloxane having at least one fluoroalkyl group per molecule, and not having a silicon atom-bonded hydrogen atom; (C) a linear organopolysiloxane having at least one fluoroalkyl group per molecule, and having neither an aliphatic unsaturated group nor a silicon atom-bonded hydrogen atom; (D) an organohydrogenpolysiloxane having at least two silicon atom-bonded hydrogen atoms and at least one fluoroalkyl group per molecule; and (E) a hydrosilylation reaction catslyst. The composition can form a release coating exhibiting a stable and low release force with respect to a silicone pressure-sensitive adhesive having a low glass transition temperature．
