Document Type and Number:
WIPO Patent Application WO/2008/038828
Kind Code:
A1
Abstract:
A highly corrosion-resistant rust-preventive coating material which comprises an
inorganic binder and zinc metal particles comprising zinc and incidental impurities,
the particles being dispersed in the binder in an amount of 30 mass% or larger based
on the dry coating film, characterized in that (i) the zinc metal particles comprise
(i-1) fine zinc metal particles which have a particle-diameter frequency distribution
constituted of one peak and a foot on each side thereof and have a peak particle
diameter of 0.05-5 µm and (i-2) coarse zinc metal particles which have a
particle-diameter frequency distribution constituted of one peak and a foot
on each side thereof and have a peak particle diameter of 6-100 µm and (ii)
the proportion of zinc metal particles having a particle diameter of 0.05-5 µm
to all zinc metal particles is 5-99 vol.%.
