Method for the manufacture of a tempered and/or bent glass pane with platinum coating or the like

Abstract From the Canadian patent

Method for the manufacture of a tempered and/or bent glass pane of soda-lime-silica glass with reduced transmission for solar radiation, in which to at least one side of the transparent glass carrier is applied a metal coating of platinum iridium, or optionally rhodium, alloys of these metals or metal alloys with a preponderant proportion of at least one of these metals in a thickness such that the light permeability of the laminate formed from the glass carrier and the metal coating is between 10 and 90%, particularly between 30 and 90% of that of the glass carrier alone and a tempering and/or bending process is performed in air at a temperature of 580 to 680°c preferably 600 to 650°C, …
