1. a curable organosilicon composition, at least comprises:

  • (A) per molecule has the organopolysiloxane of the thiazolinyl of at least two silicon bondings;

    (B) per molecule has the organopolysiloxane of the hydrogen atom of at least two silicon bondings, and its amount makes the hydrogen atom of the described silicon bonding in this component be 0.1 to 10 mole relative to the content of described thiazolinyl of every 1 mole in component (A);

    (C) the equal particle diameter of the matter of at least one type is the fine powder of 0.1nm to 5 μ

    m, be selected from;

    the zinc oxide fine powder that surface-coated has the zinc oxide fine powder of the oxide compound of at least one element be selected from Al, Ag, Cu, Fe, Sb, Si, Sn, Ti, Zr and rare earth element and/or oxyhydroxide, the silicoorganic compound process without thiazolinyl is used on surface, and the fine powder of zinc carbonate hydrate, its amount counts the 1ppm to 10% of described composition with mass unit;

    And(D) catalyst for addition reaction of hydrogen and silicon of significant quantity.
