Neodymium magnets coatings are used to protect the neodymium magnets. Neodymium magent is easy to react to oxygen and oxidizes quickly if untreated. That’s why all neodymium magnets are covered with a protective coating, which is so thin that it doesn’t have any impact on the adhesive force of the magnet.

Black 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. Black epoxy has a very good adhesion to steel with magnet rated glue. Epoxy coating is mainly colored in black, however, can be colored in white.
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.
