Abstract:
A curable organosiloxane composition comprising:(A) an organopolysiloxane having at least two silicon atom-bonded alkenyl groups per molecule; (B) an organopolysiloxane having at least two silicon atom-bonded hydrogen atoms per molecule; (C) an organosilicon compound of the formula where X is an alkenyl group; Z is an oxy group expressed by the formula â€”Oâ€”, a carboxy group expressed by the formula â€”C(O)Oâ€”, or a phenylene group, A is a divalent hydrocarbon group, a group expressed by the formula â€”R4â€”Oâ€”R4â€”where the R4 groups are divalent hydrocarbon groups, or a group expressed by the formula â€”R5â€”Oâ€”where R5 is a substituted or unsubstituted divalent hydrocarbon group, R1 is an alkyl group or alkoxy group, the R2 groups are monovalent hydrocarbon groups having no aliphatic unsaturated bonds, the R3 groups are divalent hydrocarbon groups or groups expressed by the formula â€”R6â€”Oâ€”where R6 is a divalent hydrocarbon group, a is 1 or 2, b is 0 to 3, m is 0 or 1, n is 0 to 2, p is 0 or 1, and q is 0 to 7; (D) a hydrosilylation reaction catalyst.
