Zinc Diethyldithiocarbamate

Home » Products » Zinc Diethyldithiocarbamate

We present quality Zinc Diethyldithiocarbamate which is a very fast primary or secondary (ultra) accelerator for natural and synthetic rubber. Our Zinc Diethyldithiocarbamate is also a very rapid accelerator for NR and SBR latticed. In addition, our Zinc Diethyldithiocarbamate is also used as an antioxidant in adhesive systems.


Main Uses

Zinc Diethyldithiocarbamate is very fast curing but too scorchy to be used as a sole accelerator in a dry rubber compound. It imparts high modulus to unfilled NR ulkanisates, is fast curing and confers good ageing. It gives absolutely non-staining vulkanisate free from odor and taste. Also known as ZDEC, it is widely used as a booster-cum-accelerator to speed up the thiazoles and sulphenamides based systems giving fast curing yet reasonable safe combinations. Mixtures of TMTD and ZDEC are valuable as fastest curing accelerator for Butyl rubber. It is also very useful for transparent rubber formulations.


Compounding Suggestion

ZDEC is used in the proportion of 0.25-0.5 PHR with 1-3phr Sulphur in dry rubber. If used as a secondary accelerator or booster, then a dosage of 0.05-1phr of ZDEC, along with MBT / MBTs dosage of 0.5-1. OPHR MBT / MBTS and 1.5 PHR sulphur, is also used.
