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, which provides the following advantages:
- Scratch protection: Delicate surfaces, such as whiteboards or magnetic glass boards, are well protected
- Waterproof: These magnets are rustproof and can be used outdoors and in wet surroundings
- Friction (only for rubberised magnets): The rubber coat substantially increases the magnetic adhesive force in shear direction
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.
