CBS is a prinary accelerator giving delayed action, a fast curing rate. Non-blooming, it is widely applied in NR, IR, reclaimed rubber, SBR, NBR and EPDM, especially for SBR, This product can be applied alone or with accelerators of thiuram, guanidines & dithiocarbamates. Because of the slight pollution caused, this product is mainly used in black/non-white products such as tires, belts & cable etc. Because of the bitterness of the product after vulcanization, it is not recommended to apply it to beverage and food containers.
25kg N.W./bag, in plastic fabric laminated kraft bags lined with plastic bags.
It may be descendent decomposed during storage, so should be kept in low temperature off heat and moisture.
