  • Coating method and coating device
    Patent number: 9744558
    Abstract: The present invention is intended to solve a problem that a coating film has an uneven thickness in the case where a coating target 1 has a stepped portion extending in a predetermined direction on its coating surface. To solve the problem, a follow-up coating is performed along the stepped portion S extending in the predetermined direction after coating of the entire coating surface of the coating target 1 so that paint mist adheres more to a relatively-recessed side of the stepped portion S.
    Type: Grant

  • Method for forming excellent multi-layer coating film
    Patent number: 9737906
    Abstract: The purpose of the present invention is to obtain a method for forming an excellent multi-layer coating film of high chroma and brightness and a rich color. With the method, color mottling does not occur easily in the coating film and the design obtained is homogeneous even without strict control of variations in film thickness during coating. The method for forming the excellent multi-layer coating film comprises: forming a metallic base coating film on the surface of the object to be coated by applying a metallic base coating containing a shiny material; then forming a color base coating film by applying a color base coating; subsequently forming a clear coating film by applying a clear coating on the color base coating film; and heat-curing the metallic base coating film, the color base coating film and the clear coating film obtained.
