Zinc dust applications are mainly used in galvanizing as an anti-corrosion substance in steel and iron, which represents 50 percent of daily uses. It is also utilized in galvanizing of metals, in brass making, paint making, and die casting of precision substances. Known as zinc powder as well, zinc dust applications is also used on roofs to decrease the growth of bacteria, mold, fungi, and other microorganisms. But is it effective?
