Good-Rite® Sodium MBT

Good-Rite® Sodium MBT (NaMBT) is a REACH-registered intermediate. It is highly valued in mining and metal processing applications, including precious metal extraction, electronics, and plating. In these applications, Good-Rite® NaMBT serves as an efficient metal chelator, metal deactivator, and ore purifier. It has a strong binding affinity for precious metal capture or extraction, resulting in improved isolation and recovery of metals. It is an excellent solution for gold capture, copper capture, silver capture, and nickel capture.

Good-Rite NaMBT 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.
