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.

PDF data sheet
These are the only waterproof neodymium magnets in our assortment. They can be permanently used outdoors, in wet surroundings or even in the water without rusting.
Thanks to the water-repellent rubber coats, these magnets can be used permanently outdoors without rusting. Therefore, they are the perfect tablecloth holders on a metal garden table.
On these magnets the casting seam is clearly visible, which is a little unaesthetic but attributed to the conditions of production and not a material defect.
