Hydrophobic coatings and methods for applying such coatings to the surface of a substrate. The method includes applying a coating composition to the surface and heating the coated surface at a curing temperature of about 300 ° C. to about 600 ° C. for about 2 hours to about 48 hours. The coating composition is applied to the surface by an application method selected from the group consisting of flow, dipping, and spraying. The coating composition includes an yttrium compound, an additive selected from the group consisting of a dispersion of cerium compound and yttrium oxide nanoparticles, a water-soluble polymer, and a solvent solution of deionized water and a water-soluble alcohol. |
