BONDED COMPOSITE OF SILICONE RESIN AND EPOXY RESIN AND A METHOD FOR MANUFACTURING THEREOF

摘要

An firmly bonded composite of a silicone resin and an epoxy resin comprising: (A) a curable silicone resin composition comprising: (A1) an organopolysiloxane resin that has a refractory index within the range of 1.45 to 1.60 and contains at least two silicon-bonded alkenyl groups having 2 to 12 carbon atoms, and not less than 30 mole percent of total siloxane units is phenylsiloxane units represented by the following formula: C6H5-SiO3/2, (A2) an organopolysiloxane that contains at least two silicon-bonded hydrogen atoms and(A3) hydrosilylation catalyst, and (B) a curable epoxy resin composition comprising:(B1) an epoxy resin that contains at least two epoxy groups in one molecule, (B2) a curing agent, and (B3) a curing catalyst. The firmly bonded composite is obtained only by curing composition (A) and composition (B) in tight contact with each other.
