Applications

1. Copper And Yellow Metal Corrosion Inhibitor: Its triazole ring adsorbs on copper and copper alloy surfaces and coordinates with the metal to form a tenacious passive film that blocks the electrochemical reactions behind corrosion, which is why water treaters specify inhibitor.

2. Additive For Automotive Coolants And Brake Fluids: Formulators use it to protect copper and brass components in engine cooling circuits, water cooling systems and brake systems from corrosion, and it also carries into industrial heat transfer and closed loop water systems.

3. Metalworking Fluid Additive For Alkaline Coolants: Against benzotriazole it lays down the same copper passivating film but dissolves and persists better in alkaline coolants, which matters where the fluid must stay stable at high pH and keep brass and bronze parts bright.

4. Metal Deactivator And Antirust Oil Additive: In lubricants it acts as a metal deactivator and corrosion inhibitor, and its oil soluble Mannich derivatives work as ash free copper inhibitors that are synergistic with phenolic antioxidants, while the parent compound serves antirust oil products.

5. Protection Beyond Copper, Steel And Silver: Alongside copper and its alloys it also protects steel, grey iron, cadmium and nickel, and metal finishers rely on it to keep brass and silver work tarnish free through storage and shipping.
