Properties: White, light gray powder or granular. The density is 1.29. Soluble in benzene, acetone, chloroform, CS2 partly soluble in alcohol, diethyl ether, CCI4 insoluble in water, gasoline alkali with lower concentration. Meeting hot water becomes to dimethylamine  ammonium CS2. Be sensitive to skin pneogaster

Application: Can be used as a single accelerator, as a secondary accelerator or as a sulphur donor in most sulphur-cured elastomers. Scorchy gives fast cure rates. Produces an excellent vulcanisation plateau with good heat aging compression set resistance in sulphurless 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 also be used as bactericide pesticide.

Packaging: 25kg plastic woven bag, paper with plastic film bag, kraft paper bag.

Storage: The product should be stored in the dry cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight. The validity is 2 years.

Note: The product could be ultrafine powder based on customer accurate requirement.
