    Application:: The product can be used to chloroprene rubber, Epichlorohydrin rubber, chlorinated polyethylene, etc., are particularly suited to non-curing system of the chlorine-butylamine Hopewell accelerator. Can often 100-500 , with the right selection system can be the best rapid curing, the whole parade security. Its products vulcanized high tensile strength, permanent deformation small for W (54-1 type polychloroprene), a non-curing system into effect significantly. It usually with zinc oxide magnesium oxide together with the use, mainly for industrial products, coating lines, shoes other clothing chloroprene rubber products.
    Packaging: 25kg plastic woven bag, paper with plastic film bag, Kraft paper bag.

    Storage: To keep the bags tightly closed in a cool, well-ventilated place at 25 max, to place the goods on the dry wooden shelf at a height of 20cm min. And to avoid from moisture, sunshine, light fires. The recommended max.shelf life is 2 years.

    Note: The product could be ultra fine powder based on customer accurate require.
