The density is 1.29. Soluble in benzene, acetone, chloroform, partly soluble in alcohol, diethyl ether, CCl4, insoluble in water, gasoline and alkali with low concentration.
Can be used as single accelerator, as a secondary accelerator or as a sulphur donor in most sulphur-cured elastomers.Gives fast cure rate. Produces an excellent vulcanization plateau with good heat aging and compression set resistance in sulphurless and EV cure systems. Good color retention is obtained in non-black vulcanization.
The product should be stored in dry and cooling place with good ventilation, avoiding exposure of the package product to direct sunlight. The validity is 2 years.
