Structural formula

Feature

This product is not highly toxic or explosive, soluble in organic solvents such as water, chloroform, benzene, toluene, etc. It can be mixed with lower alcohols and ethylene glycol in any ratio.

Use

BTA-S adsorbs onto metal surfaces to form a thin film, protecting copper, brass, bronze, and other metals from atmospheric and harmful media corrosion. Adding trace amounts of BTA-S to cold water can prevent the migration of copper ions, which can catalyze the corrosion of metals such as aluminum and iron. In heat transfer media, copper ions can cause aluminum pore corrosion. Adding BTA-S to the circulating water can prevent severe corrosion caused by copper ions catalyzing the oxidation of ethylene glycol to form acids. Therefore, solar energy conversion systems, cooling systems for nuclear power plant reactors and power plant boilers, as well as cooling systems for automotive engines and internal combustion engines, are widely used. The combination of BTA-S and other corrosion inhibitors has a synergistic effect. Increase its corrosion inhibition effect.
