Copper dimethyldithiocarbamate

Copper dimethyldithiocarbamate (CAS 137-29-1), also known commercially as Cumate, Wolfen, and Methyl Cumate, is an organometallic dithiocarbamate compound with the formula C6H12CuN2S4. It carries no assigned E-code and is registered under EC number 205-287-8. The abbreviation CDDC is commonly used in technical literature.

In rubber vulcanisation, it functions as an ultra-accelerator, activating sulfur cross-linking at lower temperatures and shorter cure times compared to standard thiazole accelerators. In agricultural and industrial preservation applications, the copper centre disrupts fungal enzyme activity, making it effective as a fungicide and material preservative in textiles, leather, and paper processing.

Copper dimethyldithiocarbamate is supplied in powder or crystalline form and falls under HS code 2930200090 for customs classification. It is subject to REACH registration requirements within the EU. Packaging formats and available technical grades should be confirmed directly with the supplier based on application requirements.
