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

Abstract

This water-repellent, oil-repellent member is obtained via, inter alia, a method having: a step for wet-coating a substrate surface with a solution that contains a solvent and an organosilicon compound comprising multiple silanol groups in the molecule; a step for drying the solvent to form and laminate a primer layer on the substrate surface; a step for wet-coating the outer surface of the primer layer with a solution containing a hydrolyzable fluorine-containing compound and a solvent, and subsequently drying the solvent, or dry-coating the outer surface of the primer layer with a hydrolyzable fluorine-containing compound obtained by evaporating the solvent from the solution; and a step for curing the hydrolyzable fluorine-containing compound to form and laminate a water-repellent, oil-repellent layer on the outer surface of the primer layer. The water-repellent, oil-repellent member is obtained by providing, on various substrates: a primer layer of a specific thickness that contains, as a main component, an organosilicon compound having multiple silanol groups in the molecule; and, on the outer surface of the primer layer, a water-repellent, oil-repellent layer of a specific thickness that contains, as a main component, the cured hydrolyzable fluorine-containing compound. The water-repellent, oil-repellent member makes it possible for a water-repellent, oil-repellent coating exhibiting superior abrasion resistance and antistatic properties to be stably and straightforwardly formed on various substrates.
