1,2,3-Benzotrialole (BTA)

1,2-Aminoazophenylene; 1,2,3-Triazaindene

1,2,3-Benzotrialole (BTA) can be absorbed on metal surface and form a thin film to protect copper and other metals. BTA can be used together with many scale inhibitors and fungi disinfectants in circulating cool water system, BTA has good corrosion inhibition effect in circulating cool water system. The dosage of 2-4mg/L is preferred. BTA can also be used as anti-discolor agent, coating additives and luboil additive.

2-Mercaptobenzothiazole (MBT)

2-MBT; 2-Benzothiazolethione

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.

Methylbenzotriazole (TTA)

Tolyltriazole

Methylbenzotriazole (TTA) can be used as corrosion inhibitor of copper and copper alloy, TTA also has corrosion inhibition for black metals. TTA is absorbed on metal surface to form a thin membrane to protect copper and other metals from corrosion of air and other harmful subjects. The membrane is more uniform. When used together with MBT, the effect is better.
