Zinc Dust
Zinc dust is a pure metal powder, which is grey in colour and is produced by condensation of purified zinc vapors. The particle shape is spherical (see the picture). Zinc dust is suitable for use in many binder formulations for the manufacture of zinc primers and shop primers, for example inorganic ethyl silicate and epoxy primers.
