  • Patent number: 10378111
    Abstract: Provided is a coated metal sheet for exterior use, having a metal sheet, and a top coat film situated on the metal sheet. The top coat film contains a resin, 0.2-15 volume percent of a gloss control agent composed of porous particles, and a delustering agent composed of primary particles. The coated metal sheet satisfies the following expressions in which, in the number-size distribution of the gloss control agent and the delustering agent, R is the number-average particle diameter (?m) of the gloss control agent, D197.5 and D297.5 are 97.5% particle diameter values (?m) of the gloss control agent and the delustering agent, Ru is the upper limit particle diameter (?m) of the gloss control agent, and T is the film thickness (?m) of the top coat film.

  • Patent number: 10370554
    Abstract: This coated metal sheet for exterior covering has a metal sheet and a top coating layer disposed on the metal sheet, the top coating layer is configured from a fluororesin and contains a gloss control agent comprising 0.01-15 vol % of microporous particles and a matte agent comprising primary particles, and the coated metal sheet satisfies the belowmentioned formulae. In the number-based particle size distribution of the gloss control agent and the matte agent, R is the number average particle size (?m) of the gloss control agent, D197.5 and D297.5 represent the 97.5% particle size (?m) of the gloss control agent and the matte agent, Ru is the upper limit particle size (?m) of the gloss control agent, and T is the top coating layer thickness (?m).
