Sodium salt of 1,2,3-Benzotriazole USES

1H-benzotriazole sodium can be adsorbed on the surface of the metal to form a thin film to protect copper, brass, bronze and other metals from atmospheric and harmful media corrosion, adding a trace of BTA-S in cold water can prevent the migration of copper from Chemicalbook, migrating copper ions can catalyze the corrosion of aluminum, iron and other metals, in the heat transfer medium, Copper ions can cause small hole corrosion of aluminum. Adding 1H-benzotriazole sodium to the circulating water can prevent the catalytic oxidation of ethylene glycol by copper ions.
