Corrosion inhibitors are substances that help prevent the deterioration of metals due to chemical reactions with their environment, particularly oxidation and moisture. They work by forming a protective layer on the metal surface or by neutralizing corrosive agents, thereby extending the lifespan of metal structures and components. These inhibitors are commonly used in various industries, including automotive, construction, and marine, to protect equipment and infrastructure. They can be applied in different forms, such as coatings, additives in fluids, or as part of a treatment process, ensuring that metals remain functional and safe over time.
