Abstract
Certain example embodiments of this invention relate to the development of temperable UV blocking coatings having enhanced UV blocking efficiency and aesthetic appearance on stock sheets of glass substrates using large-scale wet coating manufacturing methods. A glass substrate is provided. A base coat is curtain coated on the glass substrate from a oxide precursor material including zinc, cerium, titanium, and silicon precursor materials. The base coat is cured. A top coat is roll coated, directly or indirectly, on the base coat, with the top coat being a sacrificial cross-linked organic polymer-based layer. The substrate is heat treated with the base coat and the top coat thereon. The base coat and the top coat are substantially uniform in thickness, and the heat treating removes substantially all of the top coat while causing substantially no cracking in the base coat.
