Abstract: A method of providing an easy-clean, water-sheeting coating on a substrate includes: abrading a surface of a substrate using an abrasive article to provide an abraded surface having a surface roughness R?a#191 in a range of from 100 nm to 3500 nm, contacting a coatable composition with the abraded surface, and removing water from the coatable composition. The coatable composition comprises silica nanoparticles and has a pH of 7.5 or less. A kit including the abrasive article and the coatable composition is also disclosed.

Abstract: A coating composition is provided comprising a) an aqueous dispersion, having a pH of less than 7.5, of silica nanoparticles having average particle diameters of 40 nanometers or less, b) an alkoxysilane oligomer; c) a silane coupling agent, and d) optionally a metal β-diketone complexing agent. The compositions may be used to prepare coated articles wherein the coating is substantially uniform in thickness, durably adheres to the substrate, and provides hydrophilic and/or antireflection surface properties to the substrate.
