Good-Rite® Sodium MBT

Aqueous Good-Rite® NaMBT is REACH registered and used as metal chelator, metal deactivator, and ore purifier in applications such as mining and metal processing (electronics or plating). It has a strong binding affinity for precious metal capture or extraction, improving isolation and recovery of metals such as gold, copper, silver, and nickel. It is also used as a corrosion inhibitor in non-ferrous mixed metal systems (including copper, aluminum, and brass), transmission fluid, coolant, hydraulic fluid, cutting fluid, antifreeze, air conditioning, and refrigeration. Additionally, Good-Rite® NaMBT may be used directly as a biocide (such as a cooling tower biocide), in the production of commercial biocides, and as a slimicide under 21 CFR 121.2505.

NaMBT is also known as sodium mercaptobenzothiazole, sodium MBT, MBT sodium salt, merkaptobenzothiazole sodium salt, sodium 2-merkaptobenzothiazole, 2-mercaptobenzothiazole Na-Salt, merkaptobenzothiazole sodium, sodium mercaptobenzothiazole, and sodium merkaptobenzothiazole.
