The cooling system of an automotive engine is a complex environment where temperature fluctuations and the presence of various metals create a fertile ground for corrosion. Protecting these critical components is essential for engine performance and longevity. Sodium Benzotriazole (CAS 15217-42-2) stands out as a key chemical additive provided by NINGBO INNO PHARMCHEM CO.,LTD., playing a vital role in safeguarding automotive cooling systems.

When used as an additive in automotive coolants, Sodium Benzotriazole works by forming a protective passive film on the surface of non-ferrous metals, particularly copper and its alloys (like brass and bronze) which are common in radiators and heat exchangers. This film acts as a barrier, preventing the electrochemical reactions that lead to corrosion. The precise formulation ensures that even under the demanding conditions of engine operation – high temperatures, pressures, and chemical exposure – this protective layer remains intact.

A significant benefit of using Sodium Benzotriazole in automotive cooling systems is its ability to prevent galvanic corrosion. When dissimilar metals are in contact within an electrolyte (like coolant), a galvanic cell can form, leading to the accelerated corrosion of the less noble metal. BTAS helps to equalize the protective potential across these different metal surfaces, minimizing these electrochemical potential differences and thus preventing galvanic corrosion. This is a critical factor in extending the life of radiators, water pumps, and other metallic parts within the cooling circuit.
