Benzotriazole – 1,2,3 (BTA) is a white to off-white crystalline powder used as a high-efficiency corrosion inhibitor, primarily for copper, brass, bronze, and their alloys. It forms a strong, invisible protective film on metal surfaces, preventing oxidation and tarnishing even under harsh environmental conditions.
Due to its excellent chelating properties and low volatility, BTA is used extensively in cooling water systems, metalworking fluids, antifreeze, lubricants, and cleaning chemicals. It provides long-term protection against atmospheric corrosion and galvanic attack, making it suitable for both industrial and commercial applications.
BTA is also employed as a stabilizer in photographic emulsions, an additive in polymer and plastic processing, and in automotive antifreeze formulations.
