Epoxy coating is excellent as a barrier for salt air and salt water. However, it can be scratched easily, it must be handled carefully during assembly. Epoxy has a very good adhesion to steel with magnet rated glue. The typical coating thickness is around 15-30 microns. The maximum operating temperature is approximately 200o C. Gluing nickel coated magnets onto steel or plastic should be done with glue or epoxies specifically designed for magnets. The main industries we typically find epoxy coating being used are marine, motor, sensors, consumer products, and automotive.
