copper corrosion inhibitor : 2-Mercaptobenzothiazole (MBT) CAS# 149-30-4

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