Beschreibung
Zusammenfassung:	A highly corrosion-resistant, rust-prevention coating material comprising: an inorganic binder; and Zn metal particles comprising Zn and unavoidable impurities and dispersed in the binder at the rate of 30 mass% or greater based on a dry coating film, wherein (i) the Zn metal particles include (i-1) fine-grain Zn metal particles of 0.05 to 5 µm peak grain diameter whose grain-diameter distribution has a grain-diameter frequency distribution with a single peak and a tail on either side of the peak and (i-2) coarse-grain Zn metal particles of 6 to 100 µm peak grain diameter whose grain-diameter distribution has a grain-diameter frequency distribution with another single peak and a tail on either side of the peak, and wherein (ii) the percentage of all Zn metal particles accounted for by Zn metal particles of 0.05 to 5 µm grain diameter expressed in volume percentage is 5 to 99%.
