BTA is a reliable corrosion inhibitor and anti-rusting agent for metals. It is effectively to protect
steel, cast iron, cadmium and nickel alloys under certain conditions. In addition, it is widely used
in the antitrust products such as gas phase corrosion inhibitor, in treating agent for recycling
water, anti-freezing agent for car, synthetic detergent, anti-dust agent for photography and as
polymer stabilizer. It can be used together with many kind of scale inhibitors and bactericide or
algaecide, show excellent anticorrosion effect in close recycling cooling water system. It has
stable corrosion inhibition, toxicity, thermal stability and chemical properties. It shows stable
deoxidisation features for acid, alkali and oxide compounds.
