Zinc Dimethyl Dithiocarbamate (ZDMC) (CAS 137-30-4) is a zinc dithiocarbamate supplied in Technical Grade as a white powder with a minimum assay of 97%, serving as a rubber ultra-accelerator for low-temperature vulcanization and as a broad-spectrum fungicide in agriculture. Its 97% min purity ensures high reactivity and consistent chemical performance in diverse industrial media.
In the rubber industry, ZDMC is valued as one of the fastest-acting dithiocarbamate accelerators, suitable for low-temperature vulcanization. It produces vulcanizates with high tensile strength and superior resistance to oxidation and aging.
In agriculture, it functions as a highly effective broad-spectrum fungicide, preventing fungal growth on fruits and vegetables. Its dual-purpose nature makes it a vital commodity in both the manufacturing and agricultural sectors.
