BTA vs TTA: Which is the Better Corrosion Inhibitor for Copper and Copper Alloys?
Leave a message
Owing to the excellent thermal conductivity and mechanical processing performance, copper and copper alloys are widely used in engine coolant systems.
However, the long term connection of copper and copper alloys with antifreeze additives, the metal surface is easily corroded.
Tolyltriazole (TTA) is an excellent corrosion inhibitor for copper, brass, bronze, and other copper alloys. Used in industrial fields like metalworking fluids, engine coolant, TTA can reduce the copper corrosion efficiently, reduce economic loss and prolong the device's life.
In engine coolant additives, to prevent the corrosion of copper and copper alloys, the widely used corrosion inhibitors are mainly benzotriazole (BTA) corrosion inhibitor, tolyltriazole (TTA) inhibitor, and their derivatives.
What is benzotriazole (BTA) corrosion inhibitor? How does it prevent copper corrosion?
Tolyltriazole (TTA) is the derivative of benzotriazole (BTA) , which is an organic corrosion inhibitor for copper and copper alloys.
TTA can form a dense and insoluble polymer film, which can prevent corrode medium like oxidation and water connecting the metal surface. The polymer film has the self-healing property that when the film layer is damaged, it can re-form a new film exhibiting good oxidation stability and thermal stability.

The polymer film has good toughness, enabling it to withstand varying pH levels, elevated temperatures, and diverse environmental conditions. Therefore, Tolytriazole is an ideal copper corrosion inhibitor.
The difference between BTA and TTA Copper Corrosion Inhibitors.

Performance |
Tenzotriazole (BTA) |
Tolyltriazole (TTA) |
|
Copper corrosion effect |
Effectively, it is a traditional copper and alloy corrosion inhibitor. |
It performs better in most conditions. |
|
Film Uniformity and Hydrophobicity |
Forming a relatively uniform film |
Forming a more uniform film, and TTA has a good hydrophobicity |
|
High-temperature stability |
Under high temperatures, the formed film is easily damaged. |
It has better high-temperature resistance and anti-oxidation performance, which is stable in high-temperature situations. |
|
Adsorption capacity: |
Relatively strong adsorption capacity |
Strong adsorption capacity, and the formation of a protective layer on the metal surface is also faster. |
As a professional lubricant additives supplier in China, Chorus can provide you with excellent performance Tolyltriazole (TTA) , which can form a protective film on the copper and copper alloys' surface to prevent corrosion. At the same time, TTA and BTA are both useful in engine coolant systems, antifreeze, and metal working fluids to protect the metals like copper, silver, lead, and nickel. When formulated with other lubricant additives, TTA and BTA can protect steel and aluminum, with excellent thermal stability.
Chorus can offer you other types copper corrosion inhibition additives, like water-soluble metal deactivator TTA-42, oil-soluble ashless corrosion inhibitor TTA-39 protecting copper and copper alloys and prolonging the device and lubricant oil using life.
TTA-42 Water-Soluble Metal Deactivator: suitable for water-based metal corrosion inhibition.
TTA-39 Oil-Soluble Metal Deactivator: suitable for metal working oils, lubricant oils.
