Characteristics
This product is non toxic, non corrosive, and non explosive. It is soluble in organic solvents such as water, chloroform, benzene, and toluene, and can be mixed with lower alcohols and ethylene glycol in any proportion.
Application
Adsorb on the metal surface to form a thin film, protecting copper, brass, bronze, and other metals from corrosion by the atmosphere and harmful media. Add trace amounts of BTA-S to cold waterIt 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 corrosion of aluminum pores. Adding BTA-S to circulating water can prevent severe corrosion caused by copper ions on the catalytic oxidation of ethylene glycol to form acid. Therefore, it has been widely used in solar energy conversion systems, cooling systems for nuclear power plant reactors and boilers, as well as cooling systems for automotive engines and internal combustion engines. BTA-S
When used in combination with other corrosion inhibitors, it has a synergistic effect and increases its corrosion inhibition effect.
