- the coating agent compositions of Examples 1 and 2 consist only of components (a) to (e), and silicone oligomers having different viscosities are used as component (b). In all cases, water repellency, water slidability and coating film durability were all good.
- the coating agent composition of Example 3 used as the component (b) a silicone oligomer having a lower viscosity than that used in Examples 1 and 2 and containing a phosphoric acid catalyst as an optional component. Is. Compared with Examples 1 and 2, water repellency, water slidability and coating film durability were improved.

- the composition of Comparative Example 2 contains the content of (b) reactive silicone oligomer in Example 3 beyond the predetermined range of the present invention. All of water repellency, water slidability and coating film durability were remarkably inferior. This is because the content of (b) with a small amount of reactive groups becomes excessive, and the unreacted component (b) remains on the base material, which reacts with dust in the atmosphere and exhibits each characteristic.

- Comparative Example 5 uses methyl silicate oligomer (average tetramer) as a comparative component of component (c). Although the water slidability and the coating film durability were good, the water repellency was remarkably deteriorated. This is because a methyl silicate having a relatively highly active methoxy group reacts with the reactive group of (b), but (b) does not cross-link between molecules and forms a ring in the molecule, thereby forming a hard coating film. It is presumed that it will not form.
- the coating composition of the present invention forms a thin film coating layer having excellent water repellency and water slidability and good coating film durability, particularly on the metal surface, painted surface or resin surface of automobile bodies and train cars. Since it forms a thin film coating layer that provides water repellency, water slidability and coating film durability, and gloss and antifouling properties, it is useful for these applications.
