摘要： A silicone gel composition, (A) 100 parts by weight of a first polydiorganosiloxane containing an average of at least two silicon-bonded alkenyl groups per molecule and having a viscosity of from 0.2 to 10 Pa·s at 25° C.; (B) at least about 0.5 part by weight of a second polydiorganosiloxane containing an average of at least two silicon-bonded alkenyl groups per molecule, wherein the second polydiorganosiloxane has a viscosity at 25° C. of at least four times the viscosity of the first polydiorganosiloxane at 25° C.; (C) an organohydrogensiloxane having the average formula R7Si(SiOR82H)3 wherein R7 is an alkyl group having 1 to 18 carbon atoms or aryl, R8 is an alkyl group having 1 to 4 carbon atoms, in an amount sufficient to provide from 0.1 to 1.5 silicon-bonded hydrogen atoms per alkenyl group in components (A) and (B) combined; and (D) a hydrosilylation catalyst in an amount sufficient to cure the composition. A silicone gel comprising a reaction product of the silicone gel composition. A kit for preparing a silicone gel composition.
