This coating agent composition has excellent water repellency and water sheeting properties, while exhibiting good application workability, wear resistance and storage stability. This coating agent composition is particularly useful for the formation of a thin coating layer on a metal surface, a coated surface or a resin surface of an automobile body or a train car for the purpose of imparting the surface with water repellency, water sheeting properties, gloss, durability and antifouling properties. Specifically provided is a coating composition which contains the following components (A)-(D): (A) 100 parts by mass of a hydrolyzable silicone resin; (B) 0.1-50 part by mass of a curing catalyst; (C) 100-5,000 parts by mass of an organic solvent; and (D) 10-150 parts by mass of a dimethyl polysiloxane which has one or more alkoxysilyl groups at each end of the molecular chain, while having a viscosity at 25°C within a specific range. |
