Accelerator ZDMC / Zinc Dimethyldithiocarbamate CAS 137-30-4

1. Accelerator ZDMC is a dithiocarbamate-based ultra-accelerator primarily used in the rubber industry for the vulcanization of natural rubber, synthetic rubber (SBR, NBR, EPDM, IIR), and latex, significantly improving the elasticity and durability of rubber products .
2. Zinc Dimethyldithiocarbamate CAS 137-30-4 serves as a secondary accelerator that activates thiazole and sulfenamide accelerators (e.g., DM), enhancing processing safety while boosting vulcanization efficiency; it can also function as a primary accelerator in specific formulations .
3. In agriculture, Accelerator ZDMC (known as Ziram) is utilized as a broad-spectrum fungicide and pesticide to protect crops (almonds, apples, grapes, tomatoes) from various fungal diseases .
4. Accelerator ZDMC is suitable for light-colored, brightly colored, and food-contact rubber products (e.g., latex goods, medical rubber items, rubber sheets) due to its excellent dispersibility, odorless nature, and non-staining properties .

1. Accelerator ZDMC must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, away from direct sunlight, heat sources, and foodstuffs .
2. Zinc Dimethyldithiocarbamate CAS 137-30-4 has a shelf life of up to 24 months (2 years) when stored in its original, unopened packaging under recommended conditions .
3. Keep Accelerator ZDMC away from incompatible materials such as strong oxidizing agents, strong acids, and substances that liberate acids, as contact can cause decomposition .
4. Personnel should wear appropriate protective equipment, including chemical-resistant gloves and safety goggles, as the compound may cause skin and eye irritation .

1. Isolate the spill area immediately and wear full personal protective equipment, including NIOSH-approved respirators and chemical-resistant clothing, when handling spilled material .
2. Collect Zinc Dimethyldithiocarbamate CAS 137-30-4 by sweeping or vacuuming without creating dust using non-sparking tools, and place into suitable closed containers for disposal .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure; notify appropriate authorities if there is any risk of contaminating watercourses, as the compound is highly toxic to aquatic life .
4. Dispose of collected material as hazardous waste through licensed chemical destruction or controlled incineration, in accordance with local, state, and federal environmental regulations .

1. Accelerator ZDMC is not classified as highly flammable, but may decompose under fire conditions, emitting toxic fumes including carbon monoxide, carbon dioxide, nitrogen oxides (NOx), and sulfur oxides .
2. Use Zinc Dimethyldithiocarbamate CAS 137-30-4 dry chemical powder, carbon dioxide (CO₂), foam, or water spray to extinguish fires involving the product; do NOT use a direct water jet as it may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus (SCBA) in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning Accelerator ZDMC due to hazardous decomposition gases .
4. During combustion, may emit irritant and toxic fumes; contain fire runoff to prevent environmental contamination, and move containers from the fire area if safe to do so .
