CAS No. 29385-43-1
Molecular formula: C7H7N3
Relative molecular mass: 133.16
Ⅰ. Performance and use
Copper corrosion inhibitor TTA can be used as a corrosion inhibitor for non-ferrous copper and copper alloys, and also has corrosion inhibition effect on ferrous metals. Copper corrosion inhibitor TTA forms a thin film on the surface of the metal to protect copper and other metals from harmful media in the atmosphere and water. Copper corrosion inhibitor TTA more uniform film, and mercaptobenzothiazole sodium (MBT·Na) compound use better.

Ⅲ. Method of use
Copper corrosion inhibitor TTA is dissolved in alcohol or alkali and added to circulating water. The concentration of this product in the water is 2 -- 10mg/L. If the non-ferrous metals in the water system have been seriously corroded, the product can be added at 5 -- 10 times the normal concentration to make the system passivate rapidly.
Ⅳ. Packaging and storage
Copper corrosion inhibitor TTA is packed in a composite plastic woven bag with a net weight of 25kg. It is protected against moisture, high temperature and sunlight and has a storage period of 12 months.
