Application: Used for NR, IR, SBR, NBR, EPDM and latex. Used as a secondary accelerator in combination with PZ and EZ. It has similar performance as MBT at curing temperature in dry rubber application. Has lower scorch and better processing safety. It is 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, it will not affect the stability of latex.

 

Packing Storage:

25kg N.W. /bag, in plastic fabric laminated kraft bags lined with plastic bags.

Store closed containers in a cool, dry, well-ventilated area. Avoid exposure to direct sunlight.
