ABSTRACT:
Zinc dust composed of generally spherical zinc dust grains and having a grain size distribution such that at least about 98% of the grains have a grain size less than 15 microns and no more than about 3% of the grains have a grain size less than 2 microns, and especially well adapted for use in corrosion-inhibiting coating compositions where thin but effective protective coatings are desired or required. The zinc dust has a metallic zinc content of about 96%-98%. The corrosion-inhibiting coating compositions, and apparatus and method for the preparation of such zinc dust are also disclosed.
