Disc magnet rubber coated Ø 22 mm, height 11,4 mm

neodymium, N42
promptly deliverable


These neodymium magnets feature a rubber coating and are suitable for permanent outdoor or underwater use. The advantages of rubber coated magnets at a glance:
  • Rust-resistant even in wet environments
  • Protection against scratches on delicate surfaces, such as whiteboards and magnetic glass boards
  • Substantially higher magnetic adhesive force in shear direction compared to neodymium magnets of similar size

Please note: The rubber coating may leave dark marks when the magnet is forcefully dragged over a surface. However, such marks can easily be removed with a moist cloth.
