摘要： PROBLEM TO BE SOLVED: To provide a surface treated material which excels in heat radiation and, in addition, is economically advantageous. SOLUTION: The heat radiating surface treated material has one or more layers of coating films on the surface of a base material (e.g. a metal) and a heat radiation rate of >=60% as the surface treated material. When the coating film of the outer layer is the one comprising at least a pigment having a heat radiation rate at a wavelength of 6 μm of >=60% and a pigment having a heat radiation ratio at a wavelength of 12 μm of >=60%, the heat radiation is better than that of the coating film containing these pigments singly. Further, when the coating film of the outer layer comprises at least carbon black and titania as the pigments simultaneously at a ratio (mass ratio) of the carbon black to the titania of 0.001-0.030, the surface treated material excels in heat radiation and is economically advantageous.

摘要： PROBLEM TO BE SOLVED: To improve the weather resistance of the baked coating film of a polyester resin crosslinked with a melamine or isocyanate crosslinking agent in no need of ultraviolet stabilizer and inhibit the premature gloss deterioration and discoloration of the polyester baked paint film of high processability. SOLUTION: Vinylidene fluoride resin is admixed into the coating film, preferably baked so that the maximum temperature may reach >=220 deg.C and the vinylidene fluoride resin may be distributed thick on the coating film surface whereby the fluorine concentration is increased higher than 5 at.% on the surface of the paint film. When this coated layer is formed as a finishing layer after the surface-treated metal plate is put in the undercoat, the objective coated metal having excellent processability and resistance to weather is obtained.

摘要： PROBLEM TO BE SOLVED: To prepare a coated metallic sheet excellent in thermal shielding properties, capable of being colored into optional color and being produced inexpensively in high productivity, high in solar heat reflectibility and optimum as building exterior materials such as lightweight roof materials. SOLUTION: One side of a metallic substrate (such as a plated steel sheet) to be applied with solar radiation is provided with a coating film containing pigment of 2 to 70 mass% in which solar heat reflectibility RE/NIR in the wavelength region of 0.8 to 2.1 μm is >=10%, and the RE/NIR of the coated face is controlled to >=20%. In the case the solar heat reflectibility TE/NIR in the wavelength region of 0.8 to 2.1 μm of the coating film is high of >=20%, a metallic substrate (such as an Al plated steel sheet) whose RE/NIR is high of >=40% is used, and, reflection from the substrate is also utilized. The back side is preferably made into the one having low emissivity of =90 deg., its contamination resistance is made excellent, and the reduction of its solar heat reflectibility caused by contamination can be prevented.

摘要： PROBLEM TO BE SOLVED: To obtain a steel sheet easy to drive screws in for joining plated steel sheets with self-drilling screws by specifying surface roughness of the side of the sheet into which screws are likely to be driven. SOLUTION: At the time of bonding the plated steel sheet by using self- drilling screws, the surface roughness of the side into which screws are supposed to be driven is controlled to 1.2 to 10 μm, preferably to 2 to 7 μm by the arithmetical mean roughness Ra. As the plating kinds of the plated steel sheet, in the viewpoints of corrosion resistance, workability or the facilitation of maintenance, galvanizing, galvannealing (zinc-5% aluminum alloy plating, Zn-9% Fe alloy plating or the like), aluminum plating and aluminum alloy plating (55% aluminum-zinc alloy plating or the like) are preferable. In this way, in the case the pointed tip of a screw is pressed against the surface of a plating film, the pointed tip of the screw is held to the part, the side slip of the tip is suppressed, and screwing can easily be executed.
