1. curable organic silicon composition, said compsn comprises following at least component:

  • (A) intramolecularly has the diorganopolysiloxaneand of at least two alkenyls;

    (B) has not homogeneity average molecular weight and by SiO 4/2Unit, R 12R 2SiO 1/2Unit and R 13SiO 1/2At least two kinds of arborescens organopolysiloxanes that the unit is formed, wherein the matter average molecular weight is converted into polystyrene standard through GPC and measures R 1Be the optional substituted univalence hydrocarbyl that does not contain aliphatic unsaturated link(age), and R 2Be vinyl and wherein in per 100 mass parts components (A), the consumption of this component is the 10-100 mass parts;

    (C) contain at least two organopolysiloxanes with the silicon bonded hydrogen atom at an intramolecularly, wherein be included in consumption in this component and be 0.1-10mol/mol in component (A) with all alkenyls that comprise (B) with the silicon bonded hydrogen atom;

    With(D) hydrosilylation catalysts of catalytic amount;

    Wherein component (B) is made up of for two kinds of arborescens organopolysiloxanes of at least 1000 difference of matter average molecular weight at least.
