What are the advantages of neodymium magnet as epoxy coating?

About the coating of powerful magnet, the common ones are zinc plating, nickel plating and epoxy resin. I believe many friends don’t understand it. Some may not have seen or heard about this coating for the first time.

Epoxy resin is a coating of resin paint on the surface of NdFeB magnet after nickel plating. Epoxy resin electrophoresis is divided into metal electrodeposition (Ni / Cu) backing + epoxy resin electrophoresis layer and direct epoxy resin plating on the magnet substrate.
