The surface treatment of bonded neodymium iron boron magnet products mainly adopts epoxy resin [electrophoresis] method. In addition, coating and surface treatment processes such as acrylic resin electrophoresis, epoxy resin spraying, Teflon spraying, Perrin deposition, vacuum impregnation can also be carried out to meet the requirements of corrosion resistance, solvent resistance, and friction resistance for daily and long-term use in different environments. The specific coating requirements can be selected and stacked according to the environmental requirements of use.

Bonded neodymium iron boron is commonly used in stepper motors, spindle motors, and various types of motors and sensors, such as stepper motors used in optical disc machines, photocopiers, and fax machines, instrument panels used in the automotive industry, electric seat adjustment motors, and airbag sensors.
