The most used rare earth neodymium magnet coatings on the market are zinc or nickel-copper-nickel. Today, I will introduce a magnet coating with better salt spray resistance - black epoxy coating.
The black epoxy coating is nickel-plated on the iron-iron-boron magnet, and then a layer of resin paint is added on the outside. The epoxy resin electrophoresis is divided into metal electroplating layer (nickel/copper) primer + epoxy resin electrophoresis layer and directly on the magnet base. Epoxy plated.
Features of NdFeB (Neodymium) magnets with black epoxy plating:
High temperature resistance 380 ℃. (Temperature resistance of non-magnets)
Solvent resistance
A variety of colors are available, we usually see black epoxy, in fact, there are other colors, but not common, such as gray, red and other colors.
No hanging point
Salt spray resistance 72H
Plating thickness 15-25um
Application of NdFeB magnet with black epoxy coating:
Elevator motor, compressor, stepper motor, brushless motor, DC motor, starter motor, DVD spindle motor, optical disc drive.
