Coating the substrate with an epoxy compound is one of the most common and the easiest way to prevent corrosion. It forms a physical barrier between the harsh environment and the substrate, thereby protecting it from getting corroded. Choosing the right epoxy which can provide good corrosion resistance is very important.
Depending on the exact conditions that will be prevalent, the epoxy coating used can be varied. For example, some epoxies provide better resistance to acidic environments, whereas some epoxies provide better moisture resistance. Also, it is important to know the temperature involved in the application, because certain epoxies can resist higher temperatures as compared to others. Hence, a proper evaluation of the exact nature of corrosion taking place in your application and a proper choice of epoxy coating, can enhance the durability and the performance of the substrates involved in your application.
