Description

Sodium Dimethyldithiocarbamate is the sodium salt of dimethyldithiocarbamic acid, a versatile organosulfur compound widely used as a key intermediate and functional additive. Its primary value lies in its role as a precursor to the widely used fungicide thiram and as an effective vulcanization accelerator in rubber manufacturing. This chemical is essential for industries requiring robust biocidal activity or precise control over polymer cross-linking processes, including agriculture, rubber production, and water treatment.

Application

• Rubber Industry: Acts as a primary or secondary ultra-accelerator for the vulcanization of natural and synthetic rubber, improving processing speed and final product properties.
• Agricultural Chemicals: Serves as a crucial chemical intermediate in the synthesis of the broad-spectrum fungicide Thiram (tetramethylthiuram disulfide).
• Water Treatment: Used as a biocide and slimicide in industrial cooling water systems and paper mill process water to control microbial growth.
• Metalworking Fluids: Functions as a corrosion inhibitor and antimicrobial agent in synthetic and semi-synthetic metalworking fluids.
• Polymer Stabilization: Employed as a stabilizer or short-stop agent in the production of synthetic polymers like SBR (Styrene-Butadiene Rubber).
• Analytical Chemistry: Utilized as a chelating agent for the spectrophotometric determination and extraction of various metal ions.

Quality Control

Our Sodium Dimethyldithiocarbamate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise chemical and physical specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee supply reliability and consistent performance for your industrial processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or decomposition. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from strong acids and oxidizing agents.
