Paint & coating of Radially oriented, anisotropic Nd-Fe-B ring magnets (NEOQUENCH-DR)
Extruded NEOQUENCH-DR is rust proof in the dry air for long time, but in the high humidy air it gets rust by moisture in the air.
Therefore rust proof coating ( surface coating ) is necessary . Daido Electronics Co., Ltd. Provides 2 kinds of coating as usage.

New Electric Depositioning ( N-ED )
What is New Electric Depositioning ( N-ED ) ?
Even conventional electro-depositioning coat has well rust resistance, new electro-depositioning coat (N-ED) persues further resistance of corrosion and chemical, oil durability. Please let us propose the coating method according to your usage.
