Sodium Mercaptobenzothiazole (MBT Na)
Properties:
Sodium mercaptobenzothiazole can be used as the copper corrosion inhibitor in circulating cool water system. The mechanism is due to the chemical absorption of MBT Na on the copper surface. Or chelation reaction between them. The dosage of 4 mg/L is preferred. Sodium mercaptobenzothiazole can also be used as a plasticizer and photometer for acid copper plating.
