摘要： Disclosed is a coating composition that can provide structural materials having hydrophilicity, excellent self-cleaning property and long service life. The present invention also discloses a method for preparing the composition, a substrate, such as a film or structural exterior material like vinyl sidings, with the applied coating composition, and a method to prepare a substrate with the coating composition. The coating composition has hydroxy group-containing inorganic particles that improve the initial hydrophilicity of conventional coating agents. Additionally, by using two types of inorganic particles having different particles diameters, the coating composition can form a hydrophilic coating layer having a contact angle with water of 30° or less. Additionally, a low boiling point organic solvent having erosive property to a substrate to be coated may be used to allow the application of the coating layer to a conventional production line for structural exterior materials without adding a separate coating line.
