Uses:A vulcanizing accellerator, it’s also an excellent secondary accelerator for thaizoles, it can be used together with other accelerators for continuous vulcanition.
Character: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 polychloroprene rubber with ETU and also be used as bactericide and pesticide.
Storage method: Keep container tightly closed in a cool, well-ventilated place, the product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight.
Packing: 25 Kg each craft bag /Plastic woven bags, paper-plastic bag, brown paper bag, or container plastic woven bags.
