Disc magnet rubber coated Ø 16.8 mm, height 4.4 mm

neodymium, N45
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.

The rubber coat around the magnets protects delicate surfaces (whiteboards, magnetic glass boards, painted magnetic walls, etc.) from scratches. The rubber magnets also leave significantly less marks on fragile cards.
Rubberised magnets can lead to discolouration on photos - please use Boston Xtra Mini round on them.

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.
