Product Description
TMTD 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).
