    摘要: The present invention relates to a method of preparing hydrophilic silicone gel adhesives by curing a silicone composition. The method includes forming the silicone composition by reacting a polyoxyethylene-organopolysiloxane copolymer having an average of at least 1 functional groups selected from, unsaturated hydrocarbon, hydroxyl, silanol, or combinations thereof and a polyoxyethylene-organopolysiloxane copolymer as cross-linker having an average of at least 2 silicon-bonded hydrogen atoms per molecule in the presence of a catalyst. The polyoxyethylene-organopolysiloxane copolymers react via hydrosilylation or coupling reaction.

    摘要: A gel having improved thermal stability is the hydro silylation reaction product of (A) an organopolysiloxane having an average of at least 0.1 silicon-bonded alkenyl group per molecule and (B) a cross-linker having an average of at least 2 silicon-bonded hydrogen atoms per molecule. (A) and (B) react via hydrosilylation in the presence of (C) a hydrosilylation catalyst and (D) a heated reaction product of iron acetylacetonate. The iron acetylacetonate is present prior to heating in an amount of from about 0.05 to about 30 weight percent based on a total weight of (A) and (B). The gel is formed using a method that includes the steps of (I) heating the iron acetylacetonate to form the (D) heated reaction product of the iron acetylacetonate and (II) combining (A), (B), (C) and (D) to effect the hydrosilylation reaction of (A) and (B) in the presence of (C) and (D) to form the gel.
