Accelerator ZBDC (Zinc Dibutyldithiocarbamate)
CAS Number: 136-23-2
Zinc Dibutyldithiocarbamate (ZBDC) is an ultra-fast dithiocarbamate accelerator used as a secondary or primary accelerator in natural and synthetic rubber systems. It provides an extremely fast cure rate at low temperatures, making it ideal for room-temperature vulcanization and latex applications. ZBDC is also used as an antioxidant synergist and heat-aging stabilizer in rubber compounds.
