The disc magnets feature rubber coating,the finished size is Ø16.8x9.4mm, they are suitable for outdoor or underwater use. The advantages of neodymium rubber coated disc magnets 16.8x9.4mm as below:
· Neodymium disc magnets with rubber coating rust-resistant even in wet environments
· Scratches are protected against on delicate surfaces, such as magnetic glass boards and whiteboards.
· Compared to neodymium magnets of similar size, neodymiium disc magnets with rubber coated have higher magnetic adhesive force in shear direction .
Warning: When the 16.8x9.4mm neodymium rubber coated disc magnets are forcefully dragged over a surface the rubber coating may leave dark marks
