Sodium Corrosion Inhibitor

Sodium benzotriazole, also known as sodium tolyltriazole, is a chemical compound used primarily as a corrosion inhibitor. It belongs to the family of benzotriazole compounds, which are widely employed in various industries to prevent corrosion and protect metals from degradation.

Benzotriazoles, including sodium benzotriazole, are effective at inhibiting the corrosion of metals such as copper, brass, and bronze. They work by forming a thin protective layer on the metal surface, which helps to prevent the oxidation and degradation of the metal when exposed to corrosive environments.

Sodium benzotriazole is commonly used in applications such as water treatment, industrial cleaning, and metalworking fluids. It is often added to cooling water systems, where it helps to protect metal pipes, heat exchangers, and other equipment from corrosion caused by water impurities and aggressive chemicals.

In addition to its corrosion inhibiting properties, sodium benzotriazole also exhibits some properties as a UV-absorber and is used in certain applications where protection against ultraviolet (UV) radiation is required. It can be found in some sunscreen formulations and is used as a component in some industrial coatings, plastics, and polymers to provide UV protection.
