Method for the manufacture of a toughened and/or bent pane with solar control coating containing platinum or the like
First Claim
1. A method for manufacturing a toughened and/or bent glass pane constructed from soda-lime-silica glass and having a reduced transmission of solar radiation consisting of the steps of:
- vacuum coating at least one side of a transparent glass carrier with a metal layer comprising at least one constituent chosen from the group consisting of;
platinum, iridium, rhodium, platinum alloys, iridium alloys, rhodium alloys at ambient temperature;
the metal layer being applied being applied in a thickness such that the light transmittance of a laminate formed from the glass carrier and the metal layer is between approximately 10 to about 90 percent of that of the glass carrier alone;
vacuum coating at ambient temperature the resultant metal layer with an oxide stabilizing layer having an oxide of at least one metal chosen from the group consisting of;
Bi, In, Ni, Sb, Sn, Ta, Ti, and Zn, the stabilizing layer being applied in a thickness of approximately 2 to about 20 mm; and
heating to bend and/or toughen the glass pane at a temperature of approximately 580°
to about 680°
C. without further steps to prevent metal migration into the glass pane to occur.

Abstract
Method for the manufacture of a toughened 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 layer of platinum, iridium or optionally rhodium, alloys of these metals or metal alloys with a majority content of at least one of these metals in a thickness such that the light transmittance of the laminate formed from the glass carrier and the metal layer is between 10 and 90%, particularly between 30 and 90% of that of the glass carrier alone and a toughening and/or bending process is performed in air at a temperature of 580° to 680° C., preferably 600° to 650° C., whereby the metal layer is applied to the substantially flat glass carrier before the toughening and/or bending process and on the side of the metal layer remote from the glass carrier an oxide stabilizing layer from or with a majority content of at least one metal oxide or mixed metal oxide, preferably from the group Bi, In, Ni, Sb, Sn, Ta, Ti and Zn is applied with a thickness of 2 to 20 nm before the toughening and/or bending process.
