White to gray powder or granule. The density is 1.29.Soluble in Benzene, Acetone, CCL2, partly soluble in alcohol, diethyl ether, CCL4, Insoluble in water, gasoline and alkali with lower concentration. Meeting hot water becomes to dimethyl ammonium and CS2.Be sensitive to skin and peogaster.

Can be used as a single accelerator, as a secondary accelerator or as sulfur donor in most sulfur-cured Elastomers. Scorch and gives fast cure rates. Produces an excellent vulcanization plateau with good heat aging and compression set resistance in sulfurless and EV cure systems. Good color retention is obtained in non-black vulcanizates. As secondary accelerator for EPDM. Maybe used as a retarded in vulcanization of polychloroprene rubber with ETU and also be used as Bactericide and pesticide.

25Kg paper-plastic film bag, Kraft paper bag and or jumbo bag.

The product should be stored in the dry and cooling place with good ventilation and should be avoid hot and sunshine.
