Chemical Name: Zinc dibutyl dithiocarbamate
STRUCTURAL FORMULA
MOLECULAR FORMULA: C6H12N2S4Zn
CAS NO: 137-30-4
Accelerator ZDMC is an ultra-promoter for natural rubber, synthetic rubber and latex. It is suitable for butyl rubber, nitrile rubber and EPDM rubber. The vulcanization temperature is approximately 100℃. It needs to be used in combination with zinc oxide and stearic acid. It has similar activity to tetramethylstannous dithiocarbamate. It is prone to early vulcanization at low temperatures and can improve the anti-burning performance by being used in combination with dithio benzothiazole. It has been approved by FDA for use in food and medical rubber products and has a bacteriostatic function, which can prevent crop diseases. It has a stimulating effect on skin and mucous membranes.

Properties
White powder (granule). No taste, no poison. Density is 1.65--2.00. Soluble in lower concentration alkali, CS2, benzene, acetone and CH2Cl2, partly soluble in chloroform, insoluble in alcohol, CCl4 and ethyl acetate.
Application
Used for NR, IR, BR, SBR, NBR, HR, EPDM and natural & synthetic latexes. Stronger accelerating power than of Accelerator TT. Strong resistance to scorching. In its handling, care should be operated, because of its increase activation and strong tendency to scorch at low temperatures (100οC). Often used as a secondary accelerator. In latex, better results are obtained when used in combination with other types such as thiazole accelerators. Used for rubber coated fabrics, latex products and rubber cement, etc.
Packaging
25kg plastic woven bag, paper wilh plastic film bag, kraft paper bag.
Storage
Keep container tightly closed in a cool, well-ventilated place. The recommended maximum storage life is 2 years when stored under normal conditions.
