COATING COMPOSITIONS FOR GLASS SUBSTRATES

摘要

The present disclosure provides a coated glass substrate, first and second coating compositions, and a process for coating the substrate. The first composition includes a source of tin, a source of fluorine, a source of titanium, and a solvent. The second composition includes a source of tin, a source of fluorine, and a solvent, and can be free of titanium. The first composition is applied to the substrate under elevated temperatures, and a first or sub layer is formed on the substrate via pyrolysis. The second composition is then applied, to form a second or top layer over the sub layer.

主权项

1. A coating composition, comprising:
a source of tin, present in an amount of 15 wt % to 50 wt %, based on the weight of the composition; a source of fluorine, present in an amount of 5 wt % to 30 wt %, based on the weight of the composition; a source of titanium, present in an amount of 2 wt % to 15 wt %, based on the weight of the composition; and a solvent.
