摘要： PURPOSE:To provide the laminated coating film capable of improving the rust preventiveness of the edge of a steel sheet and the finished state after overcoating by controlling the lowest melt viscosity of an electrodeposition coating material, forming the coating film with a specified electrodeposition coating composition and applying a specified intermediate coat on the coating film. CONSTITUTION:The lowest melt viscosity of the coating film when cured obtained from the logarithmic decrement measured by a pendulum viscoelasticity measuring device is controlled to >=0.2, and the coating film is formed by the resin having the following composition. Namely, the coating film is formed from (A) the block isocyanate-cured amine-added epoxy resin, (B) the colloidal silica-contg. gelled fine grains obtained by dispersing a mixture of the acrylic copolymer contg. a hydrolyzable alkoxysilane group and a cationic group and cationic acidic colloidal silica in water and cross-linking the groups in the grain and (C) the epoxy cationic electrodeposition coating composition having the alkyltin ester compd. of a liq. aliphatic carboxylic acid. An intermediate coat having the coating film cure initiating time of 15-20min obtained by the above-mentioned measurement is applied on the electrodeposition coating film to obtain the laminated coating film.

摘要： PURPOSE:To enhance the edge corrosion resistance of a steel plate and the sharpness of top coat painting by applying top coat wherein the curing start time of a paint film calculated by measuring the logarithmic attenuation factor thereof is 15 - 20min to an electrodeposition film having a specific surface. CONSTITUTION:In order to enhance edge corrosion resistance, the center line mean roughness Ra of the roughness curve measured at a cut-off wavelength of 0.8mm of an electrodeposition painting surface is prescribed to 0.3mum or more and, from the finish properties due to top coat, Ra of the electrodeposition painting surface is prescribed to 0.8mum at the max. and the sum SIGMAP0.5mm > of power spectrum values at a wavelength of 0.5mm or less by surface frequency analysis is prescribed to 80muV or less. Ra is prescribed to 0.8mum or less at the max. because the smoothing of the roughness up to 0.3mum of the electrodeposition painting surface is possible in the case of intermediate coat whose curing start time is 12 - 15min corresponding to Ra of the electrodeposition painting surface and the curing start time measured according to an OPA method and the smoothing of roughness up to Ra of 0.8mum is possible in the case of intermediate coat of 15 - 20min. Further, SIGMAP0.5mm > is prescribed to 80muV or less because smoothing is possible at 80muV or less in the case of the intermediate coat of 15 - 20min in the same way as Ra and roughness equal to or more than 80muV can not be smoothed fundamentally by the intermediate coating.
