20080199622 | TRANSPARENT COLORLESS GLASS OR GLASS-CERAMIC PANEL HAVING AN OPTICALLY DENSE COLORED COATING AND METHOD OF MAKING SAME - A transparent, colorless glass or glass-ceramic panel has a visually dense, high-temperature-stable coating having an organic/inorganic network structure containing filling material particles and a color-imparting pigment. The mechanically stable, visually dense coating has no melt-reaction zone at the surface of the panel, which is coated with the coating, so that it does not impair the panel strength. The inorganic network structure can be made from a SiO | 08-21-2008 |
20090155585 | LEAD-FREE AND CADMIUM-FREE GLASS FOR GLAZING, ENAMELLING AND DECORATING GLASSES OR GLASS-CERAMICS - A lead and cadmium free glass for decorating and enamelling glasses or glass-ceramics having a small coefficient of thermal expansion is disclosed comprising the following components (in wt.-%): Σ(Li | 06-18-2009 |
20090305032 | Glass ceramic plate - A low-expansion glass ceramic plate, in which a black coating is applied directly or indirectly to at least some areas of at least one side of the plate and the coating contains precious metal. In order to produce a glass ceramic plate of this type that is opaque, while simultaneously retaining a sufficient degree of its thermal stability, according to this invention, the precious metal content in the coating is ≧50 wt. %, the bismuth oxide content in the coating is at most 20 wt. %, and the layer thickness of the coating is at least 200 nm. | 12-10-2009 |
20100167035 | Scratch-resistant silicone coating for cooktops made of glass or glass ceramic - A functional element, in particular a cooktop or control panel, having a flat substrate composed of or of glass or glass ceramic, in which a coating that contains a crosslinked polysiloxane is applied to the substrate. In order to improve the scratch resistance of such a coating, according to this invention, a covering layer that contains an uncrosslinked polysiloxane is applied to the coating. | 07-01-2010 |
20100219176 | COATING FOR ONE OR MORE DISPLAY AREAS ON A GLASS OR GLASS-CERAMIC PLATE, PROCESS FOR PRODUCING SAID COATING, AND USES THEREOF - The transparent coating for one or more display areas of a glass or glass-ceramic plate is made by a process using a sol-gel paint containing alkyl silicates as binding agents. The transparent coating is provided on areas of the glass or glass-ceramic plate that have been left uncoated by a color-imparting opaque coating and is formed by applying the sol-gel paint to the areas left open and then thermally treating the sol-gel paint so as to cross-link reactive groups of the alkyl silicates. The coating has organic, non-hydrolyzable groups bound directly to silicon. A process for making the coating and the uses of the coated glass or glass-ceramic plate are part of the invention. | 09-02-2010 |
20100323162 | GLASS CERAMIC PANEL WITH A PLEASING BLACK DECORATION APPLIED WITH A DECORATIVE PAINT - Decorative paints are typically burned in at relatively high temperatures, preferably in connection with the thermal ceramicizing process. In order to provide a glass ceramic panel having a cooking surface with a pleasing deep black, very smooth decoration by a burned-in decorative paint, the glass ceramic panel is formed from a melt that is black and the decorative paint on the black glass ceramic panel consists of a colorless zinc-containing glass flux The colorless zinc-containing glass flux preferably has a composition in wt. %: Li | 12-23-2010 |
20130224493 | TRANSPARENT LITHIUM GLASS-CERAMIC MATERIAL, PRODUCTION AND USE THEREOF - A lithium-containing, transparent glass-ceramic material is provided. The material has low thermal expansion and has an amorphous, lithium-depleted, vitreous surface zone. The zone is at least 50 nm thick on all sides and encloses a crystalline interior, which has high transmission. The material includes a transition region connecting the zone and the interior. | 08-29-2013 |
20130309448 | COATING BASED ON POLYURETHANE FOR DISPLAY REGIONS - Transparent coating, the process for producing the coating and its use for display regions of shaped polymer, glass or glass-ceramic bodies, where the transparent coating is a baking polyurethane system. | 11-21-2013 |
