Water-proof neodymium magnets: rust-proof & with scratch protection
The neodymium magnets in this group are entirely coated by a layer of rubber or plastic, or even shrink-wrapped into a plastic cover, which provides the following advantages:
- Waterproof: These magnets are rustproof and can be used outdoors and in wet surroundings or even washed if necessary
- Friction (only for rubberised magnets): The rubber layer significantly increases the magnetic force in shear direction
- Scratch protection: Delicate surfaces, such as whiteboards or magnetic glass boards, are well protected
Due to the rubber or plastic coating, the maximum adhesive force of these magnets is slightly lower, however, compared to similar-sized neodymium magnets without coating.
