<p>PURPOSE: Provided is a coating film formation method in which sogging etc. do not occur even in an atmosphere of low temperature and high humidity, the orientation of metallic pigment can be controlled particularly in case of using water-borne metallic paint and air-conditioning energy can be largely reduced in a 3-coat-1-bake coating film formation method using a water-borne paint. CONSTITUTION: In a coating film formation method in which the thermosetting water-borne color paint(A) is coated on the surface of the substrate, then a thermosetting water-borne paint containing color pigment and/or glittering pigment(B) is coated on the coated surface, and, after predrying as necessary, a thermosetting clear paint(C) is coated and after that the 3-layer coating films of (A),(B) and (C) are simultaneously cured by heating, the solid content of the wet coat is controlled by an air jet step in which the air, whose temperature and/or humidity are controlled, is jetted from behind the paint nozzle in approximately the same direction as the atomized particles of the thermosetting water color paint(A) move to the surface of the substrate, when the paint is coated, around the spray pattern so that the air touches the pattern.</p> |
