Epoxy (Ni+Cu+Ni+BE)


The standard nickel-plated epoxy neodymium magnets is not enough to withstand outdoor humid conditions, and the magnet materials will be corroded. Users often look for magnetic solutions for outdoor applications. Black epoxy resin coating has a good barrier effect on salt air and salt water, neodymium magnet with epoxy coating has excellent moisture-proof and corrosion resistance. If you will use NdFeB magnets outdoors or in humid environments, epoxy coated neodymium(NdFeB) magnets are good choice. Epoxy coating is more durable and nonslip than NiCuNi three-layer coating.


Neodymium magnets with epoxy coating usually have a black and smooth appearance, epoxy magnets are called black epoxy magnets, but neodymium magnets with epoxy coating also have a white luster. However, the surface of a neodymium magnet with epoxy coated is easy to be scratched and must be handled carefully during assembly. Epoxy coated neodymium magnets can be glued onto other surface with magnetic glue.

Epoxy Neodymium Magnets Characteristics

Epoxy coated neodymium magnets are generally finished on the basis of zinc or nickel plating.


Epoxy coating is divided into electrophoretic epoxy and spray epoxy. Electrophoretic epoxy coating has strong binding force, uniform thickness, salt spray resistance, acid and alkali resistance. Electrophoretic epoxy-coated neodymium magnets have hanging spots on the surface. Rare earth neodymium magnets with epoxy coating are most commonly black in color. Epoxy-sprayed neodymium magnets have no suspension points but have poor gloss. Multiple spraying can maximally meet the surface protection requirements of neodymium magnets.
