Benzotriazole (BTA, CAS 95-14-7) is a heterocyclic organic compound widely used as a corrosion inhibitor, metal deactivator, and UV stabilizer across industrial, automotive, and chemical sectors. UAB An Group Export supplies it in technical and purified grades, matched to each customer's process and application requirements.

It is used across metalworking and corrosion protection, automotive and aviation fluids, photography and imaging chemicals, polymer UV stabilization, and electroplating. Its ability to form a stable, protective complex on copper and copper-alloy surfaces makes it the industry-standard corrosion inhibitor for non-ferrous metals across a wide range of industrial applications.

For industrial buyers, supply is coordinated around grade, purity, volume, packaging, and delivery destination, in line with applicable product and transport regulations. Bulk and commercial orders are both handled — send your requirements and we'll prepare a quote covering supply, packaging, logistics, and delivery.

Key Applications

Corrosion Inhibition — Copper & Non-Ferrous MetalsThe industry-standard inhibitor for copper, brass, and bronze surfaces across cooling water systems, metalworking fluids, and industrial process equipment. Forms a stable chemisorbed protective film that prevents oxidative corrosion and tarnishing.

Automotive & Aviation FluidsUsed as a corrosion inhibitor and metal deactivator in antifreeze, coolant formulations, hydraulic fluids, and aircraft deicing fluids.

Metalworking FluidsUsed in cutting fluids, grinding fluids, and other metalworking formulations to protect non-ferrous metal components and tooling.

Photography & ImagingUsed as an antifoggant and stabilizer in photographic developer and imaging chemical formulations.

Polymer UV StabilizationUsed as a UV absorber and stabilizer in select polymer and coating formulations requiring light stability.

Electroplating & Surface TreatmentUsed in electroplating baths and metal surface treatment formulations as a brightener and stabilizer.

Water TreatmentUsed in industrial cooling water and closed-loop water systems as a copper corrosion inhibitor.
