SILICONE GEL COMPOSITION AND PRODUCED SILICONE GEL

摘要

PROBLEM TO BE SOLVED: To provide a silicone gel composition having excellent tack. SOLUTION: The composition contains (A) 100 pts.wt. polydiorganosiloxane containing at least two alkenyl groups on average bonded to a silicon atom in the molecule and having a viscosity at 25 deg.C of 0.2-10 Pa.sec; (B) at least 0.5 pt.wt. polydiorganosiloxane containing at least two alkenyl groups on average bonded to a silicon atom in the molecule and having a viscosity (at 25 deg.C) at least 4 times that of component A; (C) an organohydrogensiloxane represented by the formula: R7Si(OSiR82H)3 (wherei n R7 is aryl or a 1-18C alkyl; and R8 is alkyl), in an amount sufficient to provide 0.1-1.5 hydrogen atoms bonded to a silicon atom for total alkenyl groups of component A and component B; and (D) a hydrosilylation catalyst in an amount sufficient to cure the composition.
