Sodium Benzotriazole(BTA.Na) CAS 15217-42-2
Sinochem is a major supplier BTA.Na & Sodium Benzotriazole supplier. Meanwhile, our firm staffs a group of experts devoted to your development of China BTA.Na & Sodium Benzotriazole.
BTA-Na refers to Sodium Benzotriazole, a common copper corrosion inhibitor.
- Corrosion Inhibition: BTA•Na is widely used in circulating cooling water systems, such as those found in power plants, nuclear reactors, and automotive cooling systems. It is often used in combination with other corrosion inhibitors and scale inhibitors.
- Anti-discoloration: BTA•Na can prevent discoloration of copper and other metal surfaces.
- Other Uses: BTA•Na can also be used as a coating additive and lubricant oil additive.

Properties: BTA•Na can be absorbed on metal surface and form a thin film to protect copper and other metals. BTA•Na can be used together with many scale inhibitors and fungi disinfectants in circulating cool water system, and it has good corrosion inhibition effect in circulating cool water system. The dosage of 2-4mg/l is preferred. BTA•Na can also be used as anti-discolor agent, coating additive and luboil additive.
Package: 200L plastic drum, IBC(1000L),customers’ requirement.
Storage: Storage for six months in shady room and dry place.
Usage：
1. BTA-Na adsorbed on metal surface to form a thin film to protect copper, brass, bronze from corrosion by atmosphere and harmful medium, it could prevent copper ion to transfer if put some BTA-Na in cold water, the transformation of copper ion could expedite the corrosion of iron and aluminum, in the heat transfer medium, copper ions can cause pitting corrosion of aluminum.
2. It could prevent serious corrosion od thylene glycol catalytic oxidation acid from copper ion if putting some BTA-Na to recycling water, so it widely used in the solar energy conversion system, reactor of nuclear power plant, the boiler of power plant, cooling system of automobile engine and engine cooling system. BTA-Na could work with other corrosion inhibitor which has a synergistic effect to increase the effect of corrosion inhibitor.
Safety protection: Copper corrosion inhibitor BTA·Na is alkaline. Pay attention to labor protection during operation and avoid contact with skin, eyes, etc. Rinse with plenty of water after contact.
About Us: With over many years as a certified BTA.Na & Sodium Benzotriazole manufacturer, we combine innovation with stringent production standards to deliver high-performance product.
