| Physical and Chemical Properties | This product is non-toxic, non-corrosive, non-explosive, soluble in water, chloroform, benzene, toluene and other organic solvents can be mixed with low alcohol, ethylene glycol in any proportion. |
| Use | BTA-S adsorbed on the metal surface to form a very thin film to protect copper, brass, bronze and other metals from atmospheric and harmful medium corrosion, in cold water to add trace BTA-S to prevent the migration of copper ions, migration of copper ions can catalyze the corrosion of aluminum, iron and other metals, in the heat transfer medium, copper ions can cause aluminum small hole corrosion. Addition of BTA-S to circulating water prevents copper ions from catalytic oxidation of ethylene glycol |
