ZINC DUST
Finely divided zinc metal used as a pigment
in zinc-rich and zinc dust/zinc oxide protective coatings for iron and
steel.
ZINC-RICH COATING
Anti-corrosive primer for iron and steel incorporating zinc dust in a concentration sufficient to provide electrical conductivity in the dried film. This enables the zinc metal to corrode preferentially to the ferrous substrate, giving galvanic protection.
