Küppersbusch is presenting two new hobs with extremely robust surfaces at the area30 trade fair in Löhne. The patented SCHOTT CERAN® Miradur™ coating permanently protects the hobs against scratching. As a result, the hardness level of the surface was improved from 6 to approx. 9.5 on the Mohs` hardness scale in a comparison with standard glass ceramic hobs.
