Abstract
A coating composition and method of making a scratch resistant UV blocking glass coating is described. The composition can include an aqueous colloidal silica. a bifunctional silanol coupling agent, tetraethylorthosilicate (TEOS), a UV absorber, and a water miscible solvent selected from glycol ethers, alkanols, keto alcohols, and combinations thereof. The molar ratio of the bi-functional silanol to TEOS is selected to provide scratch resistance coupled with water resistance.
