Rubber Accelerator ZDBC (BZ)
Identification:
Chemical Name: Zinc dibutyl dithiocarbamate
Synonym: Accelerator bz; bis(n,n-dibutyldithiocarbamato)zinc
CAS NO.: 136-23-2
Structural Formula:
Molecular Formula: C18H36N2S4Zn
Properties: White powder (granule). The density is 1.24. Soluble in CS2. benzene, chloroform, alcohol, diethyl ether,insoluble in water and low concentration alkali. Good storage stability.

Application: Used for primary or secondary ultra-accelerator in NR. IR, BR, SBR, NBR, HR. EPDM, and their latexes. Similar in property to PZ and EZ. less accelerating effects than PZ and EZ to dry rubber. Effectively used in both natural and synthetic latexes for faster curing at normal (low) temperature than with PZ and EZ, and less scorching and blooming.
Packing & Storage:
25kg plastic woven bag, paper with plastic film bag, kraft paper bag, or jumbo bag.
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 2 years.
