Abstract
All-in-one formulations for preparing repellent coatings on surfaces of substrates include (i) one or more reactive components that can form a bonded layer on a surface in which the bonded layer comprises an array of compound each compound having one end bound to a surface and an opposite end extending away from the surface; (ii) an optional catalyst; (iii) a solvent; and (iv) a lubricant. A repellent coating can be formed from such formulations on substrate surfaces by drying the formulation on the surface to substantially remove the solvent and to form a bonded layer on the surface with the lubricant stably adhered to the bonded layer. The formulations can be applied to surfaces of ceramics, glasses, metals, alloys, composites, polymers or combinations thereof such as ceramic or metal plumbing fixtures, surfaces of glass substrates including mirrors, windshields, windows, surfaces composed of one or more polymers, medical devices such as ostomy appliances, etc.
