Epoxy Coated Magnets

Epoxy (Ni+Cu+Ni+BE)

Nickel-plated epoxy coated ring magnets are not suitable for outdoor use as they are not able to endure humid conditions, which can lead to corrosion of the magnet materials. In such situations, users need to search for magnetic solutions that can be utilized for outdoor applications. The black epoxy resin coating offers a commendable barrier against salt water and salt air. Neodymium magnets with epoxy coatings are ideal for outdoor and humid environments as they are equipped with excellent moisture-proof and corrosion-resistant properties. When compared to the NiCuNi three-layer coating, epoxy coating is more resilient and slip-resistant, making it a superior choice for outdoor applications with NdFeB magnets.

Neodymium magnet 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 epoxy coated countersunk magnets with epoxy coated is easy to be scratched and must be handled carefully during assembly. epoxy coated disc magnets can be glued onto other surface with magnetic glue.

Epoxy Coated Magnets Application

The marine industry is one of the main industries that often use epoxy magnets. Epoxy coated neodymium magnets are used in a variety of ways to store and secure items in and around ships.

Epoxy coated rare earth neodymium magnets are also used in motors, sensors, and automotive equipment. The neodymium magnets can withstand the moisture that may be encountered in these applications.

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.
