    Application: It can be used as a single accelerator, as a secondary accelerator or as a sulphur donor in most  sulphur-cured elastomers. Scorchy and gives fast cure rates. Produces an excellent vulcanisation plateau with good heat aging and compression set resistance In sulphurless and EV cure systems. Good color retention is obtained in non-black vulcanisation. A valuable secondary accelerator for EPDM. May be used as a retarder in the vulcanisation of polychloroprene rubber with ETU.

    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 and fires. The recommended max.shelf life is two years.
     
    Package: 25kg or 20kg paper bag or PP weaved bag lined with plastic bag. Or to be packed as required..
