COATING METHOD AND APPARATUS FOR COLOR CLEAR COATING ON BUILDING PLATE AND BUILDING PLATE

摘要

PROBLEM TO BE SOLVED: To provide a coating method and a coating apparatus for applying a color clear coating to a building plate at high coating efficiency without coating unevenness and to provide a building plate. SOLUTION: The method is used for electrostatically applying a color clear coating material 4 having a color to a building plate 5 coated at least with a top coat. When electrostatic coating is carried out, minus electric charge is applied to the color clear coating material 4 until the material reaches a jetting nozzle 22. The charged particles 41 of the color clear coating material 4 are jetted out of the jetting nozzle 22 toward the building plate 5 charged with plus charge. The flow direction of the charged particles 41 is controlled by a pair of inductor bars 3 installed between the jetting nozzle 22 and the building plate 5.
