Description

Benzothiazole-2(3H)-Thione, Copper Salt (2+) is a coordination compound formed from the reaction of 2-mercaptobenzothiazole with a copper source. This product is valued for its role as a highly effective vulcanization accelerator and stabilizer in the rubber and polymer industries. It is primarily needed by manufacturers of specialty elastomers, industrial rubber goods, and as a potential corrosion inhibitor or catalyst precursor in chemical synthesis.

Application

• Rubber Vulcanization Accelerator: Acts as a primary or secondary accelerator to enhance the speed and efficiency of sulfur vulcanization in various elastomers.
• Polymer Stabilizer: Used to improve the thermal and oxidative stability of synthetic polymers and plastics during processing and service life.
• Corrosion Inhibitor: Functions as an effective additive in coatings, lubricants, and metalworking fluids to protect ferrous and non-ferrous metals.
• Catalyst Precursor: Serves as a starting material or ligand in the synthesis of coordination complexes for catalytic applications.
• Antifouling Agent: Employed in marine paints and coatings to prevent the growth of organisms on submerged surfaces.
• Agricultural Chemicals: Used as an intermediate in the synthesis of certain fungicides and pesticides.

Quality Control

Our Benzothiazole-2(3H)-Thione, Copper Salt (2+) is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity and performance. A comprehensive Certificate of Analysis (COA) detailing assay, identification, and impurity profiles is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption and potential caking.
