Abstract: A method of forming a glass sheet comprises: (a) forming a ribbon of glass from molten glass with a pair of forming rollers; (b) reducing horizontal temperature variability of the ribbon of glass to be 10° C. or less across 80 percent of an entire width of the ribbon of glass before the ribbon of glass cools to a glass transition temperature; (c) controlling a cooling rate of the ribbon of glass while the ribbon of glass moves vertically downward within a setting zone such that the ribbon of glass has a first average cooling rate before the ribbon of glass cools to the glass transition temperature and a second average cooling rate after the ribbon of glass cools to the glass transition temperature, the first average cooling rate being less than the second average cooling rate; and (d) separating a glass sheet from the ribbon of glass.

Abstract: The disclosure herein relates to articles and related methods that utilize hybrid polysiloxane coatings to increase the strength of an armored substrate. In one embodiment, a hybrid polysiloxane coated armor substrate can comprise i) a hybrid polysiloxane coating which includes a polysiloxane epoxy polymer having 20% to 90% siloxane content by weight; and ii) an armor substrate coated with the hybrid polysiloxane coating. The hybrid polysiloxane includes chemical components, e.g., the polysiloxane epoxy polymer, that are covalently bonded to the armor substrate.
