摘要:
Provided is a liquid curable silicone elastomer composition comprising: an organopolysiloxane (A) comprising organopolysiloxane (A1) containing at least 2 alkenyl groups bonded to silicon atom per molecule and having a total alkenyl content of from 0.01 to 1.5 mmol/g, and organopolysiloxane (A2) containing at least 2 alkenyl groups bonded to silicon atom per molecule and having a total alkenyl content of from 5.0 to 15.0 mmol/g; an organopolysiloxane (B) comprising organopolysiloxane (B1) containing at least 2 silicon-bonded hydrogen atoms per molecule, and optional organopolysiloxane (B2) containing at least 2 silicon-bonded hydrogen atoms per molecule; a platinum based catalyst (C); an inhibitor (D) selected from the group consisting of acetylenic alcohols and their derivatives; and a silica filler (E). The silicone elastomer prepared by the composition have hardness ≥75 Shore A.
