    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.

    摘要: An aryl group-containing siloxane composition is formed by introducing an alkaline earth- metal as a part of the reaction product of an organopolysiloxane having at least two alkenyl groups per molecule and an organopolysiloxane having at least two silicon-bonded hydrogen atoms per molecule in the presence of a hydrosilylation catalyst, wherein at least one of the organopolysiloxanes includes an aryl group. The alkaline earth metal may be introduced via a heat stability composition or may alternatively be pre -reacted with the organopolysiloxane having at least two alkenyl groups per molecule. The aryl group-containing siloxane compositions may be utilized as an encapsulating layer for a light emitting device.
