20090162695 | SUBSTRATE WITH ANTIMICROBIAL PROPERTIES AND PROCESS FOR OBTAINING SUCH SUBSTRATE - A process for the production of a substrate having antimicrobial properties, including depositing a mixed layer on a substrate by sputtering under vacuum, the mixed layer containing at least one antimicrobial agent and a binder material selected from metal oxides, oxynitrides, oxycarbides, carbides, diamond like carbon and nitrides, where mixed targets are used for depositing the mixed layer. Substrates with mixed layers. Substrates made by the invention processes. | 06-25-2009 |
20090324990 | SUBSTRATE WITH ANTIMICROBIAL PROPERTIES - Substrate with Antimicrobial Properties An antimicrobial substrate (glass, ceramic or metallic) coated on at least one of its surface with at least one mixed layer deposited by a sputtering under vacuum magnetically enhanced process is described. The layer comprising at least one antimicrobial agent mixed to binder material chosen amongst the metal oxides, oxynitrides, oxycarbides or nitrides. This substrate present antimicrobial properties, in particular bactericidal activity even when no thermal treatment has been applied. If a tempered and antimicrobial glass is required, the same co-sputtering process can be used, optionally an underlayer can be added. Antimicrobial properties are maintained even after a tempering process. | 12-31-2009 |
20100092771 | BENDING OF GLASS SHEETS - The present invention relates to a glazing comprising an assembly of thin layers having at least one conductive metal layer and dielectric layers, in which at least one dielectric layer located under a metal layer is deposited by a high-power pulsed magnetron sputtering process (HPPMS). | 04-15-2010 |
20110081542 | SUBSTRATE WITH ANTIMICROBIAL PROPERTIES - A process for the production of a substrate having antimicrobial properties is described. It comprises a step consisting of the déposition of a métal non-gelling layer comprising an inorganic antimicrobial agent, starting from a precursor, in métal, colloid, chelate or ion form on at least one of the surfaces of the glass substrate; and a step consisting of the diffusion of the agent into said at least one surface of the substrate by thermal treatment. Alternatively, the substrate may be coated with an underlayer or a topcoat and the diffusion occurs either in the underlayer or in the topcoat. Glass and metallic substrates having antimicrobial properties are also described. In particular, a substrate exhibiting a bactericidal activity measured in accordance with standard JIS Z 2801 of higher than log 2. | 04-07-2011 |
20130057951 | SOLAR CONTROL GLAZING WITH LOW SOLAR FACTOR - The present invention relates to a substrate carrying a multilayer solar control stack, as well as to a multiple glazing incorporating at least one such sheet of glassy material carrying a solar control stack. The multilayer solar control stack comprises at least n functional layers based on a material which reflects infrared radiation and (n+1) transparent dielectric coatings such that each functional layer is surrounded by transparent dielectric coatings, n being greater than or equal to 3. The stack comprises at least one layer of metallic nature absorbing in the radiation which is visible inside the stack. The invention applies particularly to the formation of solar control glazings with low solar factor. | 03-07-2013 |
20130059137 | SOLAR CONTROL GLAZING - The present invention relates to a substrate carrying a multilayer solar control stack, as well as to a multiple glazing incorporating at least one such sheet of glassy material carrying a solar control stack. The multilayer solar control stack comprises three functional layers based on a material which reflects infrared radiation and four dielectric coatings such that each functional layer is surrounded by dielectric coating. The geometrical thickness of the second functional layer starting from the substrate is less by at least 4% than the geometrical thicknesses of the first and third functional layers. The invention applies particularly to the formation of high-selectivity solar control glazings. | 03-07-2013 |
