Abstract:
This coated metal plate is a chromate-free coated metal plate for exterior applications, which comprises a metal plate and a coating film that is arranged on the metal plate. The coating film contains 0.2-15 vol % of porous particles as a gloss control agent, and contains 0.2-15 vol % of primary particles as a matting agent. If R1 (μm) is the number average particle diameter of the gloss control agent, R2 (μm) is the number average particle diameter of the matting agent, T (μm) is the film thickness of the coating film, σ1 (μm) is the standard deviation of the number-based particle size distribution of the gloss control agent and σ2 (μm) is the standard deviation of the number-based particle size distribution of the matting agent, the coated metal plate satisfies the following formulae. (R1+2σ1)/T≤0.7 R1≥2.0 2.0≤(R2+2σ2)/T≤7.0 13≤T≤20.
