METHOD OF MAKING A HEAT-TREATED COATED GLASS ARTICLE USING A POLYMER DISPERSION

摘要

A temporary protective coating is provided over a coated glass substrate. The temporary protective coating is applied in an aqueous dispersion then solidified on the substrate. The temporary protective coating is then removed by treatment with a basic solution. In certain example embodiments, the temporary protective coating is applied after heat treatment before the coated substrate is coupled to another substrate to form a window unit such as an IG window unit or a laminated vehicle windshield.
