摘要： PURPOSE:To enable an electrically conductive bonding of a steel material plated with zinc or a zinc-base plating material without detriment to the excellent corrosion resistance of the plated steel material. CONSTITUTION:An adhesive contg. both a conductive and a corrosionproof pigments is used. The conductive pigment gives the adhesive electrical conductivity required for electrodepostion coating or grounding. The corrosionproof pigment prevents the occurrence of rust due to the function of sacrificial protection of zinc plating and thus helps a zinc-plated steel material to keep the weather resistance.

摘要： PURPOSE:To execute the fusing and film forming of a powder coating material in a short period of time and to prevent the discoloration arising from coating on a rear surface and overheating of a primer coating material and the degradation in properties by applying liquid on the surface of a steel plate in either before or after a stage for supplying the coating material to this surface, and heating the liquid with a heater partly having an induction heating section. CONSTITUTION:The liquid is applied on the surface of the metallic plate either before or after the supply of the powder coating material or the powder coating material is mixed with the liquid and the mixture thereof is applied thereon. The coating is then heated by the heater having the induction heating section in at least a part thereof by which the evaporation of the liquid and the baking of the resin are executed. Namely, the powder coating material is sprayed without imparting static electricity thereto in the case of application of the liquid before the coating material and the powder coating material is applied by the coating device for the coating material in the case of the application of the powder coating material after mixing the material with the liquid. The application is executed by an electrostatic coating method in the case of the application of the powder coating material before the liquid. Then, heating is executed. The liquid exists in gaps while there are the gaps in such a case. The heating is effectively executed by the induction heating. The effective heating is executed by the induction heating in either case even in spite of the absence of the liquid when there are no more gaps.

摘要： PURPOSE:To improve the adhesion of a film and the corrosion resistance of an end surface or damaged part by once applying a specific adhesive to the surface of a steel plate after conventional substrate treatment and subsequently laminating a fluoroplastic film to the coated steel plate. CONSTITUTION:A fluoroplastic film 5 is laminated to the surface of a zinc type plated steel plate, aluminum type plated steel plate or stainless steel plate 1 subjected to phosphate treatment and/or chromate treatment 2 through an adhesive layer 4 containing an epoxy resin, an acrylic resin and fluoroplastic as adhesive components to obtain a laminated steel plate. The adhesive layer 4 may be provided to the laminated steel plate through a polyester or epoxy type primer layer 3. By forming a colored adhesive layer by the use of the above mentioned adhesive coating solution to which color pigment is added, a colored laminated steel plate can be also obtained. The laminated film may be a film composed of arbitrary fluoroplastic and both of a colored film containing color pigment and a transparent film containing no color pigment may be used.

摘要： PURPOSE:To produce a joint product of a coated steel sheet with a required adhesive strength even if bonding is conducted at a high speed by placing a liq. product having a sufficient ability to wet the coated steel sheet at the interface and jointing the coated steel sheets with a hot-melt adhesive. CONSTITUTION:In a method wherein two adherends at least one of which is a coated steel sheet are jointed together with a hot-melt adhesive, a contact between the hot-melt adhesive and the coated steel sheet is performed in such a way that a liq. product having a sufficient ability to wet the coated steel sheet is placed at the interface. Bonding using the hot-melt adhesive is performed by inserting the hot-melt adhesive in, e.g., film form between the adherend and heat-pressing them. In addition, if the liq. product is placed in advance between the adherend and the hot-melt resin, it is possible to suppress occurrence of bubbles in the subsequent bonding work.

摘要： PURPOSE:To improve the design properties of fingerprint resistance by a method wherein protrusions of resin having a given size are formed on the surface of a metallic sheet, and a colored film layer is formed between the protrusions on a steel sheet. CONSTITUTION:An oxidation film 12 being a light interference film is formed on the upper surface of a base material 10 and resin layers 16 being protrusions are formed in a discontinuous manner, or the oxidation film 12 is first formed, and the resin layers 16 being protrusions are formed in a discontinuous state thereon. It is necessary that the number of resin protrusions being resin islands is one or more per 1mm , and an area ratio is limited to approximately 5-95%. This constitution enables production of a stainless steel high in design properties having excellent fingerprint resistance wherein a metallic touch peculiar to a colored stainless steel is prominently expressed is provided.

摘要： PURPOSE:To obtain paint film with its wettability under control by hardening the coating containing at least two components after application by contact with the solid and liquid having a specific surface tension. CONSTITUTION:The coating material having acrylic resin and fluororesin mixed together, after application, is hardened by contact with an appropriate resin film larger in surface tension than the fluororesin, preferably close to the acrylic resin. A large surface energy of the resin film forces the fluororesin smaller in surface tension into the paint layer and, in the place thereof, the acrylic resin having the surface tension close to this surface energy is collected on the interfacial side with the resin film, thereby thickening an acryloyl group on the surface side. This offers a coating film surface good in wettability and easy in top coat applicability.

摘要： PURPOSE:To enhance irradiation efficiency and to form a highly sharp film by bonding an ultraviolet ray pervious film to the ultraviolet ray curable paint applied to a base material in an uncured state to irradiate said paint with ultraviolet rays and, after removing the film, again irradiating the paint with ultraviolet rays. CONSTITUTION:In a plate to be painted such as a plate for a household electric product or a building material, a base material is coated with ultraviolet ray curable paint at first and, when said paint is in an uncured state, an ultraviolet ray pervious film is bonded to the coating surface of the base material. Then, the film is irradiated with ultraviolet rays to partially cure the film. After the film is removed, the coating surface is again irradiated with ultraviolet rays to perfectly cure the film. Since enhanced smoothness can be imparted to the film by this method, a highly sharp film is obtained. Since ultraviolet rays are allowed to directly irradiate after the film is partially cured, the irradiation efficiency of ultraviolet rays is well.

摘要： PURPOSE:To improve the adhesiveness in painting, corrosion resistance and fingerprint resistance by regulating the grain size of silica emulsified in water within the specified large-sized area in the method of adding colloidal silica onto the chromate film on a galvanized steel material. CONSTITUTION:The chromate film contg. aqueous colloidal silica having 40-100mmu grain size preferably in such a manner that the weight ratio of SiO2/CrO3 is regulated to 0.2-5 is formed on the surface of the steel material to which a zinc or zinc alloy galvanized layer is provided. In this case, a chromate treatment soln. contg. water colloidal silica having said grain size in such a manner that the weight ratio of SiO2/CrO3 in the chromate film is regulated to 0.2-5 and in which Cr occupies 20-60% of the total Cr content is applied to the surface of said steel material. In a suitable manner, the Cr adhesion ratio of said chromate film is regulated to 20-150mg/m .
