Tolyltriazole (TTA)

Tolyltriazole and its related Na salts do belong to the most effective corrosion inhibitors for copper and copper alloys. It does further show positive effects in protection of steel, gray iron, cadmium and nickel. Only workable and chemical quite identical alternative is the 1,2,3 Benzotriazole – information on this substance are available here: https://connectchemicals.com/en/product-finder/123-benzotriazole-bta

Tolyltriazole can be used in different applications in major industries. For example, it is used in cooling water or boiler systems by the industrial water treatment industry. Tolyltriazole can be also used in coolants or antifreeze products. Another application is the use as an additive in industrial lubricants, like e.g. drilling and cutting fluids. It does also work to protect silver ware in dishwashing tablets and can be further used in metal detergents.

How does Tolyltriazole work?

As a corrosion inhibitor, Tolyltriazole decreases the corrosion rate of metals and alloys. This works by forming a coating, a passivation layer, which prevents access of the corrosive substance to the metal or alloy underneath. This is of particular importance in industries where fluids routinely need to be in continuous contact with metals that require protection.

The product does show outstanding thermic and oxidative stability and is also resistant to UV light. It does not negatively affect the appearance of the metal it's applied to.

Tolyltriazole is very bright in color so that solutions – either aqueous or in different solvents – are clear and almost colorless. A table of solubility properties and max concentrations is available on request.
