CAS No.: 29385-43-1

Item Description:

It is one of the most effective corrosion inhibitors for copper and copper alloy used in various industries. Further positive effects can be seen in protection of steel, gray iron, cadmium and nickel. As a corrosion inhibitor, Tolytriazole 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.

Applications:

Tolytriazole 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. 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.
