The rubber coating makes these anti-slip and powerful magnet systems the ideal choice for use on delicate surfaces.
The magnet systems – colloquially also called pot magnets – are equipped with heteropolar NdFeB magnets that are fully encased in a layer of rubber (technical term: elastomer). This rubber casing offers a number of benefits. It not only protects delicate surfaces against scratching, but also prevents oxidation of the highly corrodible magnets through moisture. At the same time, the rubber increases the magnet’s displacement forces and prevents slippage. The rubber coated pot magnets are temperature-resistant up to 140 °F. The rubber coating also protects them against moisture and spray water. However, the permanent outdoor use of rubber coated magnets is not recommended.
The pot magnets are available with black or white rubber coating.
