Zinc Diethyldithiocarbamate (ZDEC)

Chemical Name: Zinc Diethyl Dithiocarbamate
English Name: Zinc Diethyl Dithiocarbamate
Chemical Formula: (C₅H₁₀NS₂)₂Zn
Molecular Weight: 361.91
Technical Standard: Hu Q/HG11-135-82

Uses: Relative density 1.49, insoluble in water, ketones, ethers, gasoline; soluble in 1% sodium hydroxide, carbon disulfide, benzene, chloroform; bitter taste. This product is a typical representative of dithiocarbamate accelerators. At 120-135°C, vulcanization speed is very fast; above 125°C, the vulcanization plateau narrows. When used with accelerator TMTD, DM anti-scorch agent, or antioxidant MB, it improves the storage performance of the rubber compound. Adding amine accelerators can greatly increase the vulcanization speed. It has a strong activating effect on butyl rubber containing accelerators M and TMTD, shortening vulcanization time, and is also an excellent activator for thiazole and sulfenamide accelerators. When used with ammonium or sodium dithiocarbamates and medium-zinc salts, it enhances vulcanization speed. In latex, as a secondary accelerator, it improves the aging performance of the resulting products. It is a super-fast universal accelerator for natural and synthetic rubber and latex, especially suitable for white and transparent products, mainly used in the manufacture of rubber shoes, cables, food-grade rubber, fiber rubber cloth, medical products, latex products, adhesives, thin sheets, and self-vulcanizing compounds.
Dosage: Generally 0.1-1 part; in latex compounds, 0.5-1 part.
Packaging: Inner plastic, outer woven kraft paper composite bag, 25KG/bag.
Storage: In a ventilated, dry place; shelf life not less than two years.
