Sodium dimethyldithiocarbamate

Sodium dimethyldithiocarbamate (CAS 128-04-1), commonly abbreviated as SDDC, is a dithiocarbamate salt supplied primarily as an aqueous solution. Known in rubber processing circles as Sanceler S, it functions as a biocide, fungicide, and accelerator across multiple industrial sectors.

In water treatment, SDDC acts as a broad-spectrum biocide and heavy metal precipitant, controlling microbial growth in cooling towers and industrial process water. It is highly effective at immobilizing dissolved metals ahead of effluent discharge.

Rubber manufacturers use it as an ultra-fast vulcanization accelerator, particularly in latex compounding where rapid cure at low temperatures is required. This makes it a critical component for specialized manufacturing processes.

In agriculture, it serves as an active ingredient or intermediate in the production of dithiocarbamate fungicides applied to crops. These applications help protect yields from various fungal pathogens during the growing season.

Textile and leather processing operations employ it as a preservative and antifungal agent to protect goods during storage and transit. This ensures that raw materials and finished products remain free from degradation.

Sodium dimethyldithiocarbamate is most commonly supplied as a 40% aqueous solution, though concentrations may vary by supplier and application requirement. Solid forms are available but less prevalent in commercial trade.

It is typically offered at technical grade, with specifications aligned to industrial end-use rather than food or pharmaceutical standards. This ensures the product meets the rigorous demands of heavy industrial applications.
