Coatings for NdFeB Magnets in Wind Energy, Electric & Hybrid Vehicles and Other Applications

LORD JMC magnet coatings are specially developed to meet needs of Neodymium (NdFeB) surface
treatment. LORD JMC neodymium magnet coatings are specially developed to meet the needs of neodymium (NdFeB) magnet surface treatment applications. NdFeB is widely applied in direct-driven permanent magnet generators and motors used in wind power, electric vehicle, industrial automation and other industries. Our JMC series neodymium magnet coatings help NdFeB materials resist high temperature, corrosion, and oil - as well as meeting insulation and hardness requirements.

Achieving high performance with NdFeB magnets often leads to safer and more reliable generator and electric motor operations. Additionally, the easy application and high environmental protection provided by LORD magnet coatings can help to simplify the overall process, raise efficiency and lower total costs.
