Properties: white or light yellow powder (granule) with a little bitter, no poison. The density is 1.50, Melting point above 170,slightly soluble in benzene, chloroform and ethanol, is not soluble in water petrol. And ethyl acetate. Good storage stability.

Usage:

It is used to be given flat, moderately fast cures in NR and SR. Also used in a wide range of general purpose rubber. Non-staining and non-discolouring in "white" socks; used as a plasticizer and retarder in polychloroethylene rubber. Secondary acceleration is usually required for synthetic polymers. Better scorch safety than MBT.

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.
