Zinc Diethyl Dithiocarbamate (ZDEC) (CAS 14324-55-1) is a Technical Grade dithiocarbamate ultra-accelerator supplied as an off-white powder at 98% purity, used to speed vulcanization in natural rubber, synthetic rubber and latex compounds, often as a secondary accelerator to thiazoles. With 98% purity, it is an industry standard for achieving high-modulus results in natural and synthetic rubber.

This off-white powder provides excellent physical properties and high heat resistance to finished rubber components. It is less prone to bloom compared to other dithiocarbamates, making it ideal for high-visibility aesthetic rubber applications.

ZDEC is particularly effective when utilized as a secondary accelerator to thiazoles, significantly reducing the curing time in industrial rubber goods. It maintains superior performance in both sulfur-cured and latex-based systems.
