In particular, a thin film coating layer is required to impart excellent water repellency, water repellency, and good coating film durability to metal surfaces, painted surfaces or resin surfaces of automobile bodies and trains. In the invention, the problem can be solved by using a coating composition having a specific composition. In the present invention, (b) 0.01 to 1.8 parts by mass of a reactive silicone oligomer, (c) 0.05 to 10 parts by mass of a predetermined silicate compound, and (a) 1 part by mass of silica particles, e) A coating comprising 30 to 300 parts by mass of an organic solvent and (d) an organic acid compound in an amount of 0.001 to 0.5 parts by mass with respect to 1 part by mass of the total of (b) and (c). Agent composition. |
