What are the Advantages of Zinc Spray Gun Coating? Pr oven Long Term Protection:  A sealed, Zinc Spray Gun coating can realistically provide 30 years of corrosion protection in rural environments and 5 to 25 years in urban and coastal areas. Severe atmospheric conditions will not rust steel protected by a zinc metalized coating. Versatility:  Coating thickness can be varied. This is important because the protection achieved is directly proportional to the weight of a zinc metalized coating. Severe atmospheric conditions and longer life require an increased coating thickness. The thickness can also vary in different areas of the same structure, such as troublesome flange edges, giving needed extra protection. Applied zinc metalized coatings will not mud crack, run or sag when applied over .006m thickness. No Drying/Curing Time: A zinc metalized coating bonds instantly allowing for immediate application of wash primers and sealers. Because there is no drying time, add...

Zinc Spray Gun Zinc Metallizing  is a versatile process which melts Zinc or Zinc   Alloy metals, and then rapidly propels the molten Zinc particles onto a prepared substrate, creating a lamellar or layered coating. Metallizing, or Thermal Spraying as it is often called, is a highly effective and proven method of corrosion prevention, giving galvanic as well as barrier coating protection to iron and steel. How does Zinc Coating work? Most protective coating systems for steel function acting as a barrier between the steel and the corrosive environment. If these passive and permeable barriers are damaged or penetrated, moisture and oxygen can reach the steel causing rust and eventual coating failure. A zinc metalized coating also offers barrier protection; however, the electrochemical relationship between zinc and steel allows a zinc coating to give cathodic protection as well. A zinc metalized coating will protect the steel galvanically: it will corrode in preference to s...
