Abstract

An all-in-one formulation for preparing a protective coating on a surface of a substrate comprises (i) one or more reactive components that can form a bond layer on the surface, where the bond layer comprises a series of compounds, each compound having one end bonded to the surface and the other end extending away from the surface; (ii) optionally, a catalyst; (iii) a solvent; and (iv) a lubricant. A protective coating can be formed on a surface of a substrate from such a formulation by drying the formulation on the surface to substantially remove the solvent and form a bond layer on the surface, where the lubricant stably adheres to the bond layer. The formulations may be applied to surfaces of ceramics, glass, metals, alloys, composites, polymers, or combinations thereof, such as surfaces of ceramic or metal sanitary wares, surfaces of glass substrates including mirrors, windscreens, windows, surfaces composed of one or more polymers, surfaces of medical devices such as ostomy appliances, and the like.
