PURPOSE: To obtain a coating film whose surface is densified and which is superior in chemical resistance by irradiating the surface of coating film with active rays to modify it before bridging of organo-polysiloxane in an applied liquid has been perfectly finished and then by baking this coating film at a high temperature. n CONSTITUTION: After an application liquid composed of an organo-polysiloxane as a main component is applied to a substrate, a surface of coating film is irradiated with active rays containing ultraviolet rays as a main wavelength component to modify the surface of the coating film. Next, this coating film is baked at 400°C or higher to form the coating film B of good adhesion, flatness and superior in chemical resistance. n COPYRIGHT: (C)1989,JPO&Japio |
