Patent ID: 8563667

Claim:
A silicone adhesive sheet comprising a silicone adhesive layer comprising the composition for thermosetting silicone resin on a substrate, wherein the composition comprises: (1) a dual-end silanol type silicone resin represented by formula (I): wherein R 1 represents a monovalent hydrocarbon group, and n is an integer of 20 to 10,000, provided that all R 1 groups may be the same or different; (2) a trialkoxysilane; and (3) a condensation catalyst comprises tetramethylammonium hydroxide, wherein a molar ratio of the SiOH groups of the dual-end silanol type silicone resin to the Si-alkoxy groups of the trialkoxysilane is 20/1 to 0.2/1, wherein the sheet is in a semi-cured state, and wherein the substrate is a release sheet.
