Abstract:
1. A method of making a glass article with an anti-smudge surface, comprising: (a) providing the glass article with a target surface; (b) providing a coating solution consisting essentially of a fluorosilane compound and a solvent that is miscible with the fluorosilane compound; and (c) atomizing the coating solution and spray-coating the target surface of the glass article with the atomized coating solution while controlling the spray-coating to form a coating layer consisting of a monolayer of a fluorosilane compound having a thickness in a range from 1 to 20 nm on the target surface; wherein the coating solution is atomized by injecting gas at a pressure in a range from 10 psi to 70 psi into the coating solution, the coating solution is sprayed using at least one of a micrometer set point in the range from 0.004 inches to 0.008 inches, a liquid pressure in a range from 0.5 psi to 5 psi, a nozzle and a nozzle exit distance to the target surface is in a range from 0.5 inches to 8 inches, and a nozzle pass width in a range from 0.5 inches to 3 inches.
