METHOD FOR PRODUCING WATER-REPELLING FILM-COATED ARTICLE, AND WATER REPELLING FILM-COATING LIQUID COMPOSITION USED FOR THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a water-repelling film-coated article having an excellent water drop-rolling property, high scratch resistance and high weather resistance in excellent productivity without needing a baking process, and to provide a composition for water-repelling coating films having long lives. SOLUTION: This method for producing the water-repelling film-coated article, comprising coating a coating liquid containing a silicone alkoxide (or its hydrolyzate) and a fluoroalkyl group-containing silane compound in a solvent (especially an alcohol) on a substrate and then drying the coated coating liquid is characterized by carrying out the coating process and/or the drying process in an acid or alkali atmosphere.
