Zinc dibutyldithiocarbamate

Zinc dibutyldithiocarbamate (CAS 136-23-2), commonly known as ZDBC, is an organozinc compound used as a secondary accelerator in rubber vulcanization and as a stabilizer in polymer processing. It delivers fast cure activation at moderate temperatures, making it a preferred choice for compounders seeking controlled processing windows. In rubber manufacturing, ZDBC functions as an ultra-accelerator.

This compound is essential for natural and synthetic rubber, particularly in latex goods, footwear, and industrial seals where consistent cure rates are critical for the final product quality. Tire and technical rubber compounders use it in combination with primary accelerators such as sulfenamides to fine-tune scorch safety and crosslink density during the manufacturing process.

In plastics processing, it acts as a stabilizer and catalyst precursor in certain polymerization systems where zinc-based coordination chemistry is required for material integrity. Personal care formulators have evaluated ZDBC as a preservation-active ingredient in specific rinse-off and leave-on systems, subject to regional regulatory compliance and safety standards.

Zinc dibutyldithiocarbamate is supplied as an off-white to pale yellow powder, with granule forms available for dust-reduced handling in industrial compounding environments. Standard commercial grades are offered at high active content, typically 98% or above. Technical grade is the predominant market form, with documentation suited to industrial procurement requirements.
