Properties: White or light yellow powder with light bitter taste. Hardly soluble in acetone, benzene,
ethanol, and carbon tetrachloride. Insoluble in water, gasoline. Decomposed in strong acid and alkali.
Applications: 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 EZ. Similar
performance as MBT at curing temperature in dry rubber application. Has lower scorch and better
processing safety. Suitable for mold curing. Require 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.
Packing: In 25kgs bag.
Storage: Keep container tightly closed in a cool, dry and well-ventilated place, avoiding exposure of the packaged product to direct sunlight.
