PEROXIDE-CURABLE SILICONE-BASED PRESSURE-SENSITIVE ADHESIVE COMPOSITION AND ADHESIVE TAPE

摘要

A peroxide-curable silicone-based pressure-sensitive adhesive composition comprising (A) a diorganopolysiloxane having silicon-bonded alkenyl groups at both molecular terminals used in amount of 100 parts by weight; (B) an organopolysiloxane resin having one or more silanol(OH) groups in one molecule and consisting of R32(OH)SiO1/2 units (where R3 independently stands for non-substituted or substituted monovalent hydrocarbon groups having 1 to 10 carbon atoms), R3 3 SiO1/2 units (wherein R3 is the same as defined above), and SiO4/2 units, used in amount of 10 to 200 parts by weight; and (C) one or more types of organic peroxide compounds used in a catalytic quantity.
