Abstract:
1. A silicon-containing curable composition comprising: as component (A), 100 parts by mass of a silicon-containing polymer having a weight average molecular weight of 3,000 to 100,000, which is obtainable by hydrolysis-condensation of an organosilane mixture comprising 5 to 50 mol % of one or more kind of (a) an organosilane represented by the following formula (1-1), 0 to 50 mol % of one or more kind of (b) an organosilane represented by the following formula (I-2), 0 to 40 mol % of one or more kind of (c) an organosilane represented by the following formula (1-3) and 0 to 50 mol % of one or more kind of (d) an organosilane represented by the following formula (1-4), wherein the total of the organosilane (b) and organosilane (c) is 5 to 60 mol %; as component (B), greater than 0 to 200 parts by mass of a prepolymer comprising two or more Si—H groups in one molecule, which is obtainable by a hydrosilylation reaction of one or more kind selected from (α) a cyclic siloxane mer compound represented by the following formula (2) and one or more kind selected from (β) a compound represented by the following formula (3) or (3′); as component (C), 0 to 30 parts by mass of a cyclic siloxane compound comprising two or more carbon-carbon double bonds having reactivity with Si—H groups in one molecule; as component (D), 0.0001 to 10 parts by mass of an organic peroxide and 0 to 1.0 parts by mass of a metal catalyst, and as component (E), 10 to 1,500 parts by mass of a filler wherein R wherein in the formula (2), R wherein in the formula (3), n represents 1 or 2.
