  • Publication number: 20210268541
    Abstract: An object of the present invention is to provide a method for producing a coated material by using a composition that can be spray-coated, and that does not run downward after coating (i.e., rheology controllable). The method for producing a coated material includes step (1) of applying an electron beam-curable composition containing an ethylenically unsaturated group-containing compound to a substrate to form a coating film that has a surface viscosity of 1 Pa·s to 300 Pa·s as measured based on an electric-field pickup method, step (2) of drying the coating film obtained in step (1) to form a dry coating film when the electron beam-curable composition contains a volatile component, and step (3) of irradiating the substrate that has the coating film obtained in step (1) or the dry coating film obtained in step (2) with electron beams in an inert gas atmosphere to form a cured coating film.

  • Patent number: 11097310
    Abstract: A paint hardening device is a device for hardening paint applied to a workpiece and includes an electron beam emission portion configured to emit an electron beam to harden the paint, and a storage chamber in which the electron beam emission portion is accommodated. The paint hardening device is configured to move the workpiece and the electron beam emission portion relative to each other while the electron beam is being applied to the paint from the electron beam emission portion in a state where an inert gas atmosphere is formed at least in an electron-beam passing region where the electron beam passes in the storage chamber, the electron beam being applied to the paint from the electron beam emission portion.

  • Patent number: 9808828
    Abstract: An electrostatic painting method includes steps of: attaching a grounded clip to an insulating workpiece; spraying water-based paint to the workpiece while moving a paint gun from a position where the painting has started in a predetermined direction to form a first band-like painting film; spraying the water-based paint to the workpiece while moving the paint gun to thereby form a second band-like painting film, in which the second band-like painting film is formed in parallel to the first painting film, and a part of the second band-like painting film overlaps the first painting film. An amount of overlap between the first and second painting films is within a range previously determined based on an influence on the water-based paint sprayed when the second painting film is formed that causes the water-based paint sprayed to be attracted to the grounded first painting film.
