| abstract |
The present invention, (A) an organopolysiloxane having at least two alkenyl groups and at least one aryl group in one molecule, (B) the general formula: XO- (C 2 H 4 O ) p (C n H 2nO ) q (YO) r- X (wherein X is a hydrogen atom, an alkyl group, an alkenyl group, an aryl group, an acryl group, or a methacryl group, provided that at least one X in one molecule is the above-mentioned An alkenyl group, an acryl group, or a methacryl group; Y is a divalent hydrocarbon group; n is an integer of 3 to 6; p and q are integers satisfying 2 ≦ p ≦ 100, 0 ≦ q ≦ 50; Curable silicone comprising at least a polyoxyalkylene compound represented by 1), (C) an organopolysiloxane having at least two silicon-bonded hydrogen atoms in one molecule, and (D) a catalyst for a hydrosilylation reaction. On emissions composition. This composition forms a cured product that is less likely to be turbid or colored even when exposed to high temperature and high humidity. |
