Rubber can be used as a kind of coating because of its elasticity, toughness, impermeability, adhesiveness and resistance.
The NdFeB magnets wrapped in rubber are waterproof and shatterproof, and they are suitable for delicate metal surfaces. Therefore, they have good corrosion resistance for outdoor use without being scratched. With NdFeB magnets inside, the magnet coated with rubber on the surface has strong retentivity.
There is a a rubber coating on the outside of the rubber coated magnet, so it has excellent durability and high friction, and can stand stably on various surfaces such as glass. The rubber coated magnet assembly is a magnet system with holes, countersunk heads, eyebolts and hooks that can be used with a range of standard fasteners and accessories.
These rubber coated magnets and assemblies with high strength and soft touch are designed for different fixing / installation applications such as furniture fixing, retail fixing, hanging artworks, keeping doors and drawers closed, fixing heavy objects (lights, equipment, exhibition fixtures, tools) and other items used in warehouses, manufacturing facilities, garages, workstations, etc.
Uncoated NdFeB magnets are easily oxidized. In order to protect NdFeB magnets from corrosion, different coatings can be used, and Ni-Cu-Ni coating is the most common one. However, it is best to use NdFeB magnets in dry indoor areas even in electroplated coatings.
If you want to use magnets in water or outdoors, rubber coated magnets are the right choice, because they are waterproof and shatter-resistant.
So where can rubber covered magnet assemblies be used?
1. In offices (e.g. magnetic whiteboards);
2. In medium and long-term outdoor use, such as in wind power field;
3. In humid environment (e.g. bathroom);
4. In underwater environment (for example, rubber coating magnet is used in aquariums to accommodate flag racks and power heads).
