BTA — Frequently Asked Questions (FAQ)

What is 1,2,3-Benzotriazole (BTA) used for?

BTA is a copper and copper-alloy corrosion inhibitor for circulating cooling water, antifreeze and metalworking fluids, forming a passivating film that protects yellow metals.

What is the recommended dosage of BTA?

1,2,3-Benzotriazole (BTA) is typically dosed at 1–5 ppm in cooling water. The exact dose depends on water quality, temperature and the overall treatment program — VCYCLETECH provides a tailored dosing recommendation.

What should I include in a 1,2,3-Benzotriazole (BTA) enquiry?

For metallurgy-specific corrosion-control selection, include system type and metallurgy; water chemistry and oxygen-entry pathway; corrosion, metal-release or deposit trends; existing treatment and monitoring method. State the proposed grade or specification, quantity, packaging and destination so the product and commercial requirements can be compared.
