Application
BTA is an anticorrosive chemical used primarily on copper, but also on iron, steel, cadmium, chromium, zinc. BTA can form covalent and coordinate-covalent linkages with metals, which
prevent attack by corrosive agents.
As an anticorrosive, BTA is used in metal working, in art restoration, and in the construction industry as a tarnish remover and a protective coating. It functions as a corrosion inhibitor in water cooling systems and in dry cleaning equipment. BTA is used in synthetic greases, lubricants, and hydraulic fluids to prevent the oxidation of these materials which is catalyzed by metal ions. In the electronics industry, it is used to treat packing materials for copper electronic parts and to extend the life of polymers that are used as insulators for copper wire
Other than as an anticorrosive, BTA is used in electrolytic processing, where the stripping of metals from copper cathodes is eased by pretreatment of the cathode with BTA. In photographic processing, BTA acts as an antifogging agent in silver-halide emulsions, restraining the developer and preventing the blackening or fogging of the image due to overdevelopment.
