More Information
Summary:Coated articles are provided comprising: (a) a substrate; (b) a porous sol-gel layer superimposed on at least one surface of the substrate; wherein the porous sol-gel layer comprises a hydrolyzed tetraalkoxysilane; and (c) a sealant layer superimposed on at least one surface of the porous sol-gel layer; wherein the sealant layer comprises an alkyltrihalosilane. The coated articles demonstrate superior abrasion resistance due to a glass-like layer formed from the combination of the porous sol-gel layer and sealant layer.
