Title:
COATED METAL PLATE, METHOD FOR PRODUCING SAME, AND EXTERIOR BUILDING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2016/024306
Kind Code:
A1
Abstract:
This coated metal plate for exterior covering has a metal plate and a top coating layer disposed on the metal plate, 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 plate 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 (μm) of the gloss control agent, D197.5 and D297.5 represent the 97.5% particle size (μm) of the gloss control agent and the matte agent, Ru is the upper limit particle size (μm) of the gloss control agent, and T is the top coating layer thickness (μm): D197.5/T ≤ 0.9; Ru ≤ 1.2T; R ≥ 1.0; 0.5 ≤ D297.5/T ≤ 7.0; and 3 ≤ T ≤ 40.
