Zinc dimethyl dithiocarbamate
ZDMC (Zinc dimethyldithiocarbamate) is a creamy-white powder for use in the rubber industry.
ZDMC OT is widely used in rubber processing as an ultra accelerator for low-temperature cures, either alone or as an activator for other accelerators, chiefly the thiazoles.
It can be used:
Without sulphur (2 – 4% on the weight of the gum)
With sulphur in conjunction with zinc oxide and fatty acid as activators (0.1 – 1 % TMTD on the weight of the gum)
In conjunction with accelerators such as mercaptobenzothiazole (0.25 – 0.5 TMTD on the weight of the gum)
