The present invention is an organopolysiloxane (A1) having two or more alkenyl groups bonded to a silicon atom per molecule and having a total alkenyl content of 0.01 to 1.5 mmol/g, and two or more alkenyl bonded to a silicon atom per molecule. An organopolysiloxane (A) containing a group and an organopolysiloxane (A2) having a total alkenyl content of 5.0 to 15.0 mmol/g; Contains at least two silicon-bonded hydrogen atoms per molecule, wherein the silicon-bonded hydrogen atoms are provided in the form of siloxy units of type (R 2 HSiO 1/2 ) x, where R is hydrogen, aliphatic hydrocar An organopolysiloxane (B1) wherein x is 2 or more, independently selected from bill, aromatic hydrocarbyl, or organyl groups; And at least two silicon-bonded hydrogen atoms per molecule, wherein the silicon-bonded hydrogen atoms are provided in the form of siloxy units of type (RHSiO 2/2 ) z , where R is hydrogen, aliphatic hydrocarbyl , Independently selected from aromatic hydrocarbyl, or organyl groups, wherein z comprises an optional organopolysiloxane (B2) of 2 or more, wherein silicon is in the form of a siloxy unit of type (R 2 HSiO 1/2 ) x -The organopolysiloxane (B) having a molar amount of bonding hydrogen greater than 40 mol% of the total silicon-bonded hydrogen atom content of the organopolysiloxane (B); Platinum-based catalyst (C); An inhibitor (D) selected from the group consisting of acetylene alcohol and derivatives thereof; It relates to a liquid curable silicone elastomer composition comprising a silica filler (E). |
