Product Data

The density is 1.31-1.34. Soluble in benzene, toluene, chloroform, CS2, CH2Cl2 acetone, ethyl acetate, hardly soluble in alcohol, insoluble in water, gasoline, acid/alkali with a lower concentration


CZ is a highly active after-effect accelerator with excellent anti-scorch performance, safe processing and short vulcanization time. In the vulcanization temperature of 138 ℃ or more when the promotion effect is very strong. It is often used as the second accelerator with TMTD, DPG or other alkaline accelerators. Alkaline accelerators such as Thiuram and dithiocarbamates can enhance its activity. Mainly used in the manufacture of tires, hoses, shoes, cables and other industrial rubber products.


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 1 year.
