  • Publication number: 20120029128
    Abstract: There is provided a practically useful aqueous resin composition which enables to obtain a coating film that is satisfactory not only in corrosion resistance but also in coating adhesion when applied over a metal surface, specifically an aqueous resin composition which enables, in a form of a thin film having a thickness of about 0.1-5 ?m, to exhibit various properties practically required for surface treating agents for chromium-free surface-treated steel plates, namely excellent corrosion resistance, adhesion to steel plates, durability against alkaline degreasing agents or solvents which are used for removing a press oil used during press molding, adhesion to an overcoating material which is used for aesthetic purposes, mechanical stability and the like. The aqueous resin composition comprises 100 parts by mass of a copolymer of an ?,?-ethylenically unsaturated carboxylic acid and an olefin; and 0.

  • Publication number: 20090130431
    Abstract: A resin film is formed on the surface of a hot dip galvanized steel sheet by applying emulsion of a polyolefin copolymer resin molecular-associated by ion cluster to the steel sheet surface. The resin film contains, in terms of solids content, 10 to 55 mass % of silica particles, 1 to 8 mass % of a crosslinking agent, and 1 to 8 mass % of tannic acid and/or ammonium vanadate. The resin-coated hot dip galvanized steel sheet is capable of exhibiting well-balanced superior characteristics in weldability, corrosion resistance, and machinability.

  • Patent number: 6927243
    Abstract: The present invention relates to a photocurable resin composition which contains a photocurable component and forms on a substrate a photocurable resin layer having a viscosity of 1000-500,000 Pa·s at 23° C. and 65% RH. This resin composition is formed into a photocurable resin layer, which is laminated onto a metal sheet to give a metal sheet with a photocurable resin layer laminated thereon. This metal sheet can be worked and converted into a metal part with a high-hardness protective coating laminated thereon upon irradiation with light or electron beams after working.

  • Patent number: 6277468
    Abstract: The present invention provides a paper-laminated metal sheet having a structure in which at least one sheet of paper is laminated on at least one side of a metal plate via a pressure sensitive adhesive agent or an adhesive agent layer, and a protective layer is formed on a top surface of the paper-laminated side. With this structure, the paper-laminated metal sheet can be processed without wetting the paper with water, while thereby preventing the paper from being torn. In addition, the aesthetic appearance derived from the paper is kept for a long period of time. Due to high strength and processability derived from the metal base material, and high aesthetic appearance unbelievable for a metal plate derived from the paper, the paper-laminated metal sheet is valuable in various applications as a novel material.
