Rubber Coated Neodymium (NdFeB) Pot Magnets .The rubber coating also provide a good level of corrosion protection in humid conditions. Because of their high performance, slide resisting properties and paint work protection ability, these rubber coated Neodymium (NdFeB) pot magnets are sometimes also known as Boutique Magnets.Rubber coating of pot magnets is considered useful when using sensitive surfaces like glass and plastics, or highly finished vehicular surfaces. Rubber coating is also useful to prevent corrosion in marine, aquatic or external environments, as well as in areas where metal strike presents a risk to the magnet. Metal strike situations are more likely in mechanical environments related to motors and machinery.Rubber coated pot magnets are often placed to create a fixing or hanging point. The rubber coating provides for superior slide resistance due to greater friction between the rubber and steel surface to which the magnet is bonded. Manufacturers and industrial designers use rubber coated pot magnets for holding and fastening.
