Zinc Dibutyl Dithiocarbamate (ZDBC, CAS 136-23-2) is an organozinc compound supplied as a white solid in Technical Grade at 99% minimum purity, acting as an ultra-accelerator for the vulcanization of NR, SBR and EPDM rubber. Featuring 99% min purity, it provides exceptional aging resistance and prevents color degradation in white or translucent products.

As an organozinc compound, ZDBC is renowned for its non-staining and non-discoloring properties in high-clarity rubber formulations. It is particularly effective as a secondary accelerator for thiazoles or sulfenamides to boost overall curing efficiency.

This chemical is widely used in the production of latex dipped goods and adhesive systems due to its high solubility in organic solvents. It enhances the mechanical performance of rubber articles subjected to extreme environmental conditions.
