摘要:
A liquid curable silicone elastomer composition is disclosed. The liquid curable silicone elastomer composition comprises an organopolysiloxane (A) containing at least two silicon-bonded alkenyl groups per molecule, an organopolysiloxane (B) containing at least two silicon-bonded hydrogen atoms per molecule, a platinum based catalyst (C), an inhibitor (D), and a silica filler (E). The organopolysiloxane (B) is a branched polymer, contains M siloxy units, and the at least two silicon-bonded hydrogen atoms are present on the M siloxy units. The inhibitor (D) is selected from the group consisting of acetylenic alcohols and their derivatives. The inhibitor (D) is present in the liquid curable silicone elastomer composition in an amount to provide a molar ratio of the inhibitor (D) to platinum in the catalyst (C)—of from 150 to 900 (150:1 to 900:1).
