Product Info

A proven corrosion inhibitor, Benzotriazole (BTA) forms a stable protective film to prevent rust and discoloration of copper, alloys, and other metals. Also used as a reagent and UV stabilizer across multiple industries.

VERZONE Crystal #120 (Benzotriazole, BTA) is a heterocyclic compound widely recognized for its excellent corrosion inhibition performance, particularly for copper and copper alloys. It chemically reacts with the metal surface to form a stable complex protective film, providing long-term resistance against corrosion and discoloration.

With a strong track record since 1962 in Japan, BTA has become an indispensable additive in metal protection, electronics, processing oils, and industrial applications. Beyond corrosion control, it is also used as a quantitative reagent for silver and as a UV stabilizer in photographic emulsions and developing solutions—demonstrating its versatility across industries.

Distributed domestically in Thailand by DAIWA FINE CHEMICALS (THAILAND) CO., LTD., VERZONE Crystal #120 supports both industrial corrosion prevention and specialized chemical applications.
