OBJECT WITH EASILY CLEANED SURFACES AND METHOD FOR PRODUCTION THEREOF

The invention relates to objects, especially glass objects or glass ceramic objects, which are provided with a double coating to facilitate cleaning thereof. In order to ensure a coating that meets very strict test conditions developed for interior panes of baking ovens, said object comprises a double coating encompassing a hydrophobic outer layer that is provided with a component which reacts with a free OH group, and an inner inorganic sol-gel layer. The outer hydrophobic layer is applied to a highly reactive inner sol-gel layer that only begins to dry at moderate temperatures of up to a maximum of 100° C. and is firmly anchored thereto in a chemical manner by means of condensation reactions, whereupon the double-layer system is burned into the surface of the object at temperatures exceeding 50° C. The inventive method accordingly comprises the following steps: an inner inorganic sol-gel layer is applied directly to the surface of the object using conventional processes in a first step; the inner sol-gel layer is dried at a temperature ranging between room temperature and 100° C.; an outer hydrophobic layer that preferably contains fluoride compounds is applied to the reactive inner sol-gel layer using previously known processes in a second step; and the double-layer system is burned into the surface of the object.
