CHEMICAL STRUCTURE:
CHEMICAL NAME: Zinc dibutyl dithiocarbamate
MOLECULAR FORMULA: C18H36N2S4Zn
MOLECULAR WEIGHT: 474.1
CAS NO.: 136-23-2
PROPERTIES:
White powder/granule. 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 PZ and EZ, and less scorching and blooming.
