Properties and Usage:

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. 2-Mercaptobenzothiazole (MBT) can also be used as plasticizer and photometer for acid copper plating.

Package and Storage:

25kg in plastic barrel, or confirmed by clients. Storage for six months in room shady and dry place.

Synonyms:

MBT; 2-MBT; 2-Mercaptobenzothiazole; 2-Benzothiazolethione

Properties:

Methylbenzotriazole (TTA) can be used as corrosion inhibitor of copper and copper alloy, it also has corrosion inhibition for black metals. Methylbenzotriazole (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.

Usage:

First, dissolved with alcohol or alkali, then added into circulating water system, the dosage of 2-10mg/L is preferred. If the metal is badly corroded, 5-10 times of normal dosage should be expected.

Package and Storage:

25kg inner liner polyethylene (PE) bag, outer plastic woven bag,, or confirmed by clients. Storage in room shady and dry place.

Properties and Usage:

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