Properties: Light yellow powder with light bitter taste. Specific density is 1.65--1.72. Hardly soluble in acetone, benzene, ethanol, and carbon tetrachloride. Insoluble in water, gasoline. Decomposed in strong acid and alkali.

Application: Used for NR, IR, SBR, NBR, EPDM and latex. May be regarded as an intermediate between MBT and MBTS. Used as a secondary accelerator in combination with PZ and ZEDC. Similar performance as MBT at curing temperature in dry rubber application. Has lower scorch and better has processing safety. Suitable for mold curing. Requires zinc oxide and stearic acid as activators in many kinds of rubber batch. Easily disperses in rubber; yields non-staining and non-discoloring products. Mainly used in the manufacture of latex products, foam rubber, latex coating gloves, etc.

Storage: Keep container tightly closed in a cool, well-ventilated place. The recommended max. storage life is 2 years when stored under normal conditions.

Packaging: 25kg/bag.
