Product Description ZDEC(ZDC EZ)-80 is a polymeric dispersion of zinc diethyl dithiocarbamate. This masterbatch dispersion has fast curing rate in NR, SBR, NBR and EPDM. It can delay the start of curing with thiuram and thiazole, and increase processing safety. Compared with ZDBC(BZ)-80, it has long scorch time and short vulcanization time. Alkaline accelerator imparts active effect to ZDEC(ZDC EZ)-80. Slight ZDEC(ZDC EZ)-80 is used as assistant accelerator for thiol or thiuram. It imparts high tensile strength and resilience to vulcanizate.


Processing Characteristics Generally, ZDEC(ZDC EZ) powder has high melting point and large particle diameter, then it is so difficult to soften and disperse at processing temperature that vulcanization activity and mechanical properties of vulcanizate lower. However, ZDEC(ZDC EZ)-80 is formed by pre-dispersing selected ZDEC(ZDC EZ) powder to binder with certain surfactant. ZDEC(ZDC EZ)-80 disperses easily in kinds of rubber compounds to keep optimal activity of ZDEC(ZDC EZ). ZDEC(ZDC EZ)-80 has good dosing property and fluidity, no irritating dust and no material loss.


Dosage NR: 0.3 ~1.0 phr;

            SBR/ NBR: 0.6 ~ 1.2 phr;

            As assistant accelerator: 0.1 ~ 0.2 phr.


Applications Widely used in EPDM seals, rubber shoes, cables, and etc..


Packaging Coextruded paper bags lined with plastic film, net weight 25Kg/bag.


Storage Store in a cool, dry, well-ventilated area away from sunlightfor up to 1 year.


Safety and toxicity Refer to related MSDS.
