Abstract:
1. A flame retardant silicone composition comprising (A) 100 parts by weight of an organopolysiloxane having at least one alkenyl group having 2 to 6 carbon atoms, in a molecule of the organopolysiloxane, represented by the following general formula (1): wherein R is an alkenyl group having 2 to 6 carbon atoms, R 1 is a substituted or unsubstituted monovalent hydrocarbon group free of aliphatic unsaturation, “a” is a positive number of 0.0001 to 0.2, “b” is a positive number of 1.7 to 2.2, and the sum of a+b is 1.9 to 2.4, (B) an organohydrogenpolysiloxane having at least two hydrogen atoms bonded to silicon atoms in a molecule, in an amount to give 0.1 to 5 silicon atom-bonded hydrogen atoms per alkenyl group in component (A), (C) a platinum catalyst in an amount to give 0.1 to 1,000 ppm of platinum element based on the weight of component (A), and (D) 0.0001 to 1 part by weight of at least one compound selected from the group consisting of indoline, benzoxazole, 2-hydroxybenzoxazole, 5-benzyloxyindole, 1,2-benzisoxazole, 2,1 -benzisoxazole, and 1,3-benzodioxole.
