This sample is a rectangular neodymium magnet with a waterproof and rust resistant coating of black epoxy on the surface, which can effectively protect rare earth neodymium magnets. The magnet has a length of 30mm, a width of 20mm, and a thickness of 5mm. The default thickness is magnetization. If you need other sizes and do not like this black coating, you can choose another one. We can meet your requirements.
About Epoxy Coating:
Epoxy coating is a coating made of epoxy resin and hardener. Often chosen as a metal coating, epoxy coatings bind well to metal surfaces to form a hard, durable barrier that can withstand a variety of chemicals and environmental conditions. They also have excellent adhesion properties, which means they are effective at protecting metal surfaces from corrosive substances without peeling or cracking over time. For example, ndfeb magnet itself is easy to corrosion and oxidation, through the epoxy coating can make NdFeb magnet waterproof, rust resistant, corrosion resistant.Compared with other anticorrosion technology, epoxy resin is a kind of cost-effective corrosion solution, because it can protect the surface of a long time.
