Abstract:
1. An adhesive silicone elastomer sheet afforded by the cure of a hydrosilylation-curing silicone elastomer composition comprising: (A) 100 parts by weight of an organopolysiloxane that contains at least one diorganosiloxane unit and that has at least two silicon-bonded alkenyl groups in each molecule, (B) 50 to 150 parts by weight of an organopolysiloxane resin with the average unit formula:  in which R (C) an organopolysiloxane that contains at least two silicon-bonded hydrogen atoms in each molecule, in a quantity sufficient to provide 0.01 to 10 moles silicon-bonded hydrogen atoms in this component per 1 mole of the total alkenyl groups in components (A) and (B), and (D) a hydrosilylation catalyst in a quantity that accelerates curing; wherein the adhesive silicone elastomer sheet comprises a separator on both surfaces, wherein each separator is peelable and each separator independently comprises polycarbonate, polyethersulfone, cellulose acetate, or polyethylene terephthalate.
