1. curable organic polysiloxane composition, it comprises:

  • (A) each molecule has at least two straight chain organopolysiloxanes with the aryl of silicon bonded alkenyl and at least one and silicon bonding;

    (B) have the organopolysiloxane of following averaging unit molecular formula;

    (R 2SiO 3/2) a(R 22SiO 2/2) b(R 23SiO 1/2) c(SiO 4/2) d(XO 1/2) eEach R wherein 2Be identical or different replacement or unsubstituted univalence hydrocarbyl, all R 20.1-40mol% be alkenyl, all R 2Be aryl greater than 10mol%, X is hydrogen atom or alkyl, a is a positive number, b is 0 or positive number, c is 0 or positive number, d is 0 or positive number, e is 0 or positive number, b/a is 0-10, c/a is 0-0.5, d/ (a+b+c+d) is 0-0.3, and e/ (a+b+c+d) is 0-0.4, Wherein, use component (B) with the weight ratio of 1/99-99/1 based on the weight of component (A);

    (C) have the organopolysiloxane of following averaging unit molecular formula;

    (R 3SiO 3/2) f(R 32SiO 2/2) g(R 33SiO 1/2) h(SiO 4/2) i(X`

    O 1/2) jEach R wherein 3Be identical or different alkenyl, replacement or unsubstituted univalence hydrocarbyl or hydrogen atom, all R 30.1-40mol% be hydrogen atom;

    All R 3Be aryl greater than 10mol%;

    X `

    is hydrogen atom or alkyl, and f is a positive number, and g is 0 or positive number, and h is 0 or positive number, and i is 0 or positive number, and j is 0 or positive number, and g/f is 0-10, and h/f is 0-0.5, and i/ (f+g+h+i) is 0-0.3, and j/ (f+g+h+i) is 0-0.4, Wherein for per 100 parts by weight of component (A) and gross weight (B), with the consumption use component (C) of 1-200 weight part;

    With(D) consumption is enough to promote said composition solidified hydrosilylation catalysts.
