Abstract (en)
[origin: WO2005044749A2] The invention relates to objects, in particular, made from glass or glass ceramic, comprising a double coating to facilitate cleaning thereof. According to the invention, a coating which meets the test conditions developed for interior oven glazing may be achieved, by means of a double coating with an outer layer, comprising components reacting with free OH groups and an inner inorganic metal oxide layer, whereby the outer hydrophobic layer is applied on a very reactive inner metal oxide layer, dried at moderate temperatures of up to 100 DEG C and chemically anchored thereto by condensation reactions and the double layer system then burned onto the surfaces of the object at temperatures above 50 DEG C. Said method is carried out with the following steps: application of an inner inorganic sol-gel layer, directly to the surfaces of the object with conventional techniques in a first step, drying the inner sol-gel layer at a temperature between ambient and 100 DEG C, application of an outer hydrophobic, preferably fluoro compound to the reactive inner sol-gel layer with a conventional method in a second step and burning the double layer system onto the surfaces of the object.
