Abstract:
A method for manufacturing a water repellent coating film, comprising providing a coating material composition comprising a material comprising a hydrolyzable group, the hydrolyzable group comprising at least one element selected from the group consisting of Si and Ti, and a fluorocarbon group in a molecule of the material, the hydrolyzable group being only on one terminal of the molecule, coating a surface of a base material with the coating material composition, and hydrolyzing the coating material composition comprising the material in an atmosphere containing relative humidity of 30-80% to provide a film comprising a microcrystalline polymer having a fluorocarbon group that is at least crosslinked by at least one bond selected from the group consisting of a siloxane bond and a titanium-oxygen (--TiO--) bond.
