Applying electroconductive heating circuits to glass by electroplating
Abstract
Abstract CONDUCTIVE METAL COATING IS SELECTIVELY DEPOSITED ON THE ROUGH, POROUS FRIT BY ELECTROLESS PLATING. THE FRIT MAY BE SENSITIZED BY INCORPORATING A MINOR AMOUNT OF A SENSITIZING METAL THEREIN OR BY APPLYING A SENSITIZING COMPOSITION. APPLYING A DECORATIVE COATING OR DESIGN OF ELECTROCONDUCTIVE MATERIAL TO A GLASS BASE. WHEN THE BASE IS TRANSPARENT, THE RESULTING ARTICLE IS USEFUL AS A READILY HEATED WINDOW FROM WHICH FOG AND ICE CAN BE READILY REMOVED ON HEATING. A FRIT COMPOSITION HAVING AN APPROPRIATE COEFFICIENT OF EXPANSION, AN APPROPRIATE MATURING TEMPERATURE, AND WHICH MATURES INTO A ROUGH, POROUS COATING IS APPLIED TO A GLASS SHEET SURFACE IN THE CIRCUIT PATTERN DESIRED, THE SHEET IS HEATED AND THEN COOLED RAPIDLY TO PRODUCE A TEMPERED GLASS SHEET HAVING A ROUGH, POROUS FRIT COATING CONFORMING TO THE PATTERN DESIRED FOR THE ELECTROCONDUCTIVE HEATING CIRCUIT, AND A
