Zinc-rich paints are those paints that contain moderately large amounts of zinc dust or zinc dust mixed with organic or inorganic binders. This zinc-rich paint is applied as a topcoat to steel or other metal surfaces that operate under harsh environmental conditions and are at constant risk of corrosion. Zinc dust prevents metal from corroding by simply sacrificing itself.
Zinc powder is a zinc material in powder form, also known as zinc dust.
Zinc is an important chemical element with atomic number 30, found in group 12 of the periodic table. It is an important sacrificial element used to control corrosion by sacrificing itself through the galvanizing process.
Zinc-rich paints are primarily used to protect metal surfaces from corrosion by providing cathodic protection, but at the expense of the zinc contained in these paints.
Zinc-rich paints and coatings are often used with the addition of a primer that acts as a secondary shield to protect the surface from corrosion.
