SOLVENTLESS RELEASER COMPOSITION FOR USE WITH SILICONE PRESSURE-SENSITIVE ADHESIVES AND RELEASE LINER

摘要

PROBLEM TO BE SOLVED: To provide a release agent composition for a solventless silicone adhesive, which can be applied to a substrate in a solventless state and gives a cured film which is excellent in adhesiveness, has a low peeling strength, and shows a small reduction in a residual adhesion rate, and to provide a release sheet in which a cured film of the composition is formed on a substrate surface.;SOLUTION: The release agent composition for a solventless silicone adhesive comprises: (A) an organopolysiloxane which has at least two alkenyl groups bonded to a silicon atom and at least one monovalent fluorine-containing substituent bonded to a silicon atom in one molecule, has a fluorine content in a molecule of 30 to 50 mass%, and has a viscosity at 25°C of 100 to 2,000 mPa s; (B) an organohydrogenpolysiloxane which has at least three hydrogen atoms bonded to a silicon atom in one molecule; (C) a reaction controlling agent; and (D) a platinum group metal-based catalyst, wherein the composition has a viscosity at 25°C of 50 to 2,000 mPa s.;COPYRIGHT: (C)2012,JPO&INPIT
