  Properties:White or light gray powder (granule). The density is 1.29. Soluble in benzene, acetone, chloroform, CS₂ partly soluble in alcohol, diethyl ether, CCI₄ insoluble in water, gasoline and alkali with lower concentration. Meeting hot water becomes to dimethyl ammonium and CS₂. Be sensitive to skin and peogaster
  
  Application: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 chloroprene rubber.
  
  Packing:25kg plastic woven bag, paper with plastic film bag, kraft paper bag
  
  Storage:The product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight. The validity is 2 years
