colored coating the foil is glued with a transparent temperature resistant adhesive to the underside of the glass ceramic panel 1 acrylate adhesive coatings for example from 3m co uv hardening adhesives or highly transparent silicone adhesives preferably 2k systems can be used as the adhesive on the underside of the glass ceramic panel 1 the laminated colored foil should be applied to the glass ceramic panel 1 in a bubble free application of the adhesive the adhesive coating must compensate for any nub or nob structures which are typically from 50 to 150 microns high thus the minimum coating thickness for the adhesive is 150 microns in those embodiments the adhesive should have a sufficiently high moisture resistance since water vapor is generated during the heating of the insulating ring of the heating element 3 the cooking surface can also be provided by a glass panel made from pre stressed special glass e g lithium aluminum silicate glass las glass or borosilicate glass instead of by a glass ceramic panel the possible coating materials for the individual sections or portions 6 a 6 b of the underside coating 6 include 1 in section 6 a for the heated region 2 a lustrous paints from heraeus d johnson matthey n l b lustrous paints which contain conventional inorganic pigments lustrous pigments metal effect pigments pearlescent pigments or interference pigments or various mixtures of these pigments c sol gel coatings or pigmented sol gel coatings which.
