  • Publication number: 20200010698
    Abstract: A method for forming a multilayer coating film is provided. The method includes coating at least one object with an aqueous primer coating composition, an aqueous first colored coating composition, an aqueous second colored coating composition, and a clear coating composition, in that order. The aqueous primer coating composition contains a component (A) which contains a polyolefin resin, a component (B) which contains a polyurethane resin, a curing agent (C) and electrically conductive carbon (D). The aqueous first colored coating composition and aqueous second colored coating composition each contain a core/shell emulsion. The clear coating composition contains a hydroxyl group-containing acrylic resin, a polyisocyanate and a melamine resin. The method improves the appearance, chipping resistance, adhesive properties and low temperature impact properties of a coating film.

  • Patent number: 10190016
    Abstract: [Purpose] Among two-component top coat paints for the automobile coatings field, wherein the base resin paint is circulated from a main tank with a pump upstream of the coating gun, and mixing and coating are effected using a curing agent supplied from a nitrogen-sealed tank and a two-component mixing device, to provide a paint composition with which problems such as thickening and gelling of the circulating base resin paint do not occur, coating is possible with a stabilized constant coating viscosity, and with which the paint film after stoving exhibits excellent Scratch resistance, stain resistance, acid resistance and gasoline resistance, and a multilayer coating formation method using this.

  • Patent number: 6331326
    Abstract: A coating film which has no problems in its film properties and is superior in hiding power for hiding sand scratches on the substrate and exhibiting a continuous plated metal-like appearance is formed in a stable manner, by coating the substrate with a primer (A) and/or a first metallic paint (B) containing non-leafing type aluminum flakes (a) having thicknesses in the range from 0.1 to 1 &mgr;m and an average particle size of 1-60 &mgr;m and, then, coating with a second metallic paint (C) containing small, thin metal flakes (b) having thicknesses not greater than 0.08 &mgr;m and an average particle size of 5-40 &mgr;m.
