Water- and oil-repellent member and method for manufacturing water- and oil-repellent member

摘要

A step of wet-coating a solution containing an organic silicon compound having a plurality of silanol groups and a solvent on the surface of the base material, a step of drying the solvent to form a primer layer, and a step of forming a primer layer on the primer layer, and a fluorine-containing compound and a solvent. After wet-coating the solution containing, the solvent is dried, or a step of dry-coating a fluorine-containing compound obtained by evaporating the solvent from the solution, and the fluorine-containing compound is cured to form a water-repellent and oil-repellent layer. After providing a primer layer having a specific thickness containing an organic silicon compound having a plurality of silanol groups as a main component on various substrates obtained by a method having a step or the like by the above method, a solvent-containing primer layer is provided on the primer layer. The water- and oil-repellent member provided with the water- and oil-repellent layer of a specific thickness containing the cured product of the compound as the main component provides a water- and oil-repellent film with excellent wear resistance to various base materials in a stable and easy manner. Further, the primer layer and the water- and oil-repellent layer can be applied by a room temperature (25 ° C.) process.
