WATER REPELLENT COATING COMPOSITION, METHOD FOR PREPARING THE SAME, AND COATING FILMS AND COATED ARTICLES USING THE SAME

摘要

A water repellent coating composition comprises fine particle having a functional group on its surface; a coupling agent containing a functional group capable of reacting with the functional group of the fine particle and a water repellent functional group; a binder resin for binding the fine particles; and a solvent for the binder. The coating composition can be used in various fields including constructions, civil engineering, transportation, communication. A coating film or a substrate and coated articles produced with the water repellent coating composition exhibit excellent water repellence, antisnow- or antiice-sticking properties, and weatherability. The method provides water repellent coating composition which can form a coating film having an improved light transmittance due to uniformly dispersed fine particles.
