Sodium 2-Mercaptobenzothiazole (sodium MBT) is utilized as a corrosion inhibitor and fungicide. By analogy to MBT, sodium MBT is identified as a skin sensitizer. Sodium 2-Mercaptobenzothiazole is also used to make rubber accelerators, as a preservative for latex paint and wood, a metal chelator, and a thermal stabilizer (methyl methacrylate copolymers, acrylonitrile polymers, polyester fibers, anion exchange resins, polyoxyphenylene, and silicon fluids), also used in electroplating (silver, nickel, and cobalt), to separate sulfide ore from copper ore, for dyeing textiles, in transmission fluids, and to prevent discoloration of freeze dried bananas; uses of 50% aqueous solution include as a corrosion inhibitor for nonferrous metals in antifreeze and coolants and in paper mill systems; used as a biocide in metalworking fluids and paper manufacturing.
