Abstract:
An enamel paste composition is provided for fabricating a coated glass article comprising a glass substrate, an enamel layer disposed on the glass substrate, and a thin coating having a thickness of no greater than 0.5 micrometres disposed on the enamel layer. The enamel paste composition is formulated such that it provides a smooth surface and does not crystallize during processing of the coated glass article, thereby improving the quality of the thin coating disposed thereon.

Abstract:
A coated glass substrate is disclosed. The coated glass substrate includes a coating containing at least one metal oxide containing a zinc oxide. The zinc of the zinc oxide is present in an amount of from 5 wt.% to 50 wt.% as determined according to XPS. The coated glass substrate has area surface roughness Sa or Sq of from about 5 nm to about 1,500 nm as determined via atomic force microscopy.
Abstract:
A glass-based frit paste is disclosed, wherein a ratio of the total weight percent of high boiling point organic material to the total weight percent of low boiling point organic materials is in a range from about 3.0 to about 5.0, and a maximum weight % of low boiling point organic materials is equal to or less than 10%. A method of forming a glass article is also disclosed. Specific sintering schedules to minimize and/or eliminate dark spots formed by incomplete burn-off of volatile paste constituents are also disclosed.
Abstract:
The invention relates to glass compositions, in particular glass compositions for enamels such as for automotive applications. The invention also relates to inks comprising the glass compositions, a method for forming an enamel coating on a substrate and a substrate with an enamel coating formed thereon. The compositions comprising SiO 2 , ZnO and Bi 2 O 3 as major constituents, typically include no boron or a low level of boron, and are typically substantially free of lead.

Abstract:
Certain example embodiments of this invention relate to coated articles including substrates that support printed patterns and thin film layer stacks that can have the patterns and the layer stacks formed thereon and then be cut, heat treated, and optionally built into an insulated glass unit, laminated to another substrate, and/or used in another product. In certain example embodiments, this is made possible by bonding to the glass the frit material used in forming the pattern, re-annealing the glass following the bonding, disposing the thin film layer stack on the re-annealed substrate supporting the bonded pattern, and then cutting and heat treating. The frit advantageously does not re-melt during heat treatment because the melting temperature is higher than the temperature used in heat treatment, and/or as a result of secondary recrystallization of the frit material. Associated methods also are provided.
Abstract:
Heavy-metal-free glass enamels are applied to glass and fired. After firing, the coated glass can subsequently be ion exchanged to give a chemically strengthened, decorated glass article.
