​Tolyltriazole (TTA) has been widely used in various industries.  TTA and its related Na salts is one of the most effective corrosion inhibitors for copper and copper alloy used.

The method of operation of this material is by sticking to the copper surface and forming a strong electrochemical barrier with a thickness of several molecules to protect the metal surface against corrosive ion attacks. This protective barrier is very stable and shows a high degree of thermal and oxidative stability, so it is not easily removed.

​Tolyltriazole corrosion inhibitor for copper


The color of TTA is so light that the solutions – either in water or in various solvents – are clear and almost colorless. ITS soluble in alcohol, benzene, toluene, chloroform and watery lye, and hardly soluble in water.

Chemical structure   ​Tolyltriazole corrosion inhibitor

TTA complexes copper by other metals to protect against galvanic corrosion. In addition to copper and NTA alloys, positive effects on the protection of steel, gray iron, cadmium and nickel

Shows against corrosion

The difference between triazole and Benzotriazole (BTA)

BTA is structurally similar to TTA, but the extra methyl group of TTA Helps solubility in some organic solvents.


It can be uses in variety applications in major industries. for example: antirust oil (tallow) products, water Colling circle systems, boilers, water treatment industry, Production of coolants or antifreeze products, additive in industrial lubricants, drilling and cutting fluids, to protect silver ware in dishwashing tablets, metal detergents.

Another important property of this compound is its high thermal and oxidative stability. In addition, it is resistant to ultraviolet rays and does not adversely affect the appearance of the metal to which it is applied.

Corrosion inhibitors

It is decreasing the corrosion rate of metals and alloys. TTA forms a coating, a passive layer, which prevents corrosive material from reaching the metal or alloy beneath it, thus preventing corrosion. This property is especially important in industries where liquids are in constant contact with metals.

Environmental hazards

It is combustible. Contact with this compound may cause eye and lung irritation.

This substance emits toxic fumes due to heating, which irritates the eyes and lungs.

TTA is not compatible with oxidizing agents. It may also be incompatible with isocyanates, halogenated organic matter, peroxides, phenols (acidic), epoxides, anhydrides and acid halides. The neutralizing reaction of this substance with acids is exothermic and causes the production of salt and water. Flammable gaseous hydrogen is produced by combination with strong reducing agents such as hydrides.
