Keywords:
- Chemical composition: Zinc dibenzyl dithiocarbamate
- Complex carrier: EPDM
- Characteristics: An ultrafast accelerator for synthetic rubbers such as NR, EPDM, IR, SBR, NBR, and IIR; it belongs to the class of secondary amine dithiocarbamate accelerators and does not generate nitrosamines during vulcanization. Typically used in conjunction with products like TBBS-80 and TBzTD-75, it forms an environmentally friendly vulcanization system. Among all zinc dithiocarbamate accelerators, this one exhibits the best scorch resistance.

Pain point you may have faced
You need fast cure to maximize throughput, but many ultra‑fast accelerators introduce serious trade‑offs: scorch during hot summer processing, nitrosamine risks that fail REACH audits, and poor compatibility with light‑colored compounds. You have tried other dithiocarbamates, but none give you the ideal balance of speed, safety, and compliance.Why ZBEC‑75 (ZTC‑75) is different
First® ZBEC‑75 (zinc dibenzyldithiocarbamate) is an ultra‑fast accelerator specifically designed for NR, EPDM, IR, SBR, NBR, IIR, and other synthetic rubbers. Because it belongs to the secondary amine dithiocarbamate family, no nitrosamine carcinogens are generated during vulcanization. More importantly, among all zinc dithiocarbamate accelerators, ZBEC‑75 offers the best scorch resistance – giving you a much wider safety window during mixing, extrusion, and storage.How to use it
ZBEC‑75 is typically used as a secondary accelerator in combination with TBBS‑80, TBzTD‑75, or other primary accelerators. Together they form a fully eco‑friendly vulcanization system that delivers fast cure, excellent safety, and full REACH compliance.What you gain
Fast cure speed – short cycle times, high productivity.
No nitrosamines – safe for the workplace and for export to regulated markets.
Best‑in‑class scorch resistance among zinc dithiocarbamates – drastically reduce scrap from premature curing.
Versatile – works in black, light‑colored, and transparent compounds without staining.
Real‑world result
A manufacturer of EPDM automotive weatherstrips was using a conventional thiuram accelerator. They experienced frequent scorch on hot days and failed a German OEM’s nitrosamine test. After switching to First® ZBEC‑75 at 0.7 phr together with TBBS‑80, scorch time increased by 45%, cure speed remained unchanged, and the nitrosamine test passed easily. The weatherstrips also showed no surface bloom.Typical specifications
