Zinc Cold-Galvanizing Spray (Bright)

What is Galvanizing?

Galvanizing is the process of applying a protective zinc coating to steel or iron to provide protection and prevent corrosion. When exposed to the atmosphere, iron reacts with the presence of oxygen and thus becomes oxidized, which is how iron corrodes. The galvanized layer creates a zinc barrier and sacrificial cathodic protection that prevent the above reactions from occurring.Like all metals, zinc corrodes when exposed to air and moisture. However, zinc corrodes approximately 100 times slower than other metals. When zinc reacts with oxygen, a thin layer of zinc oxide is formed. When this zinc oxide reacts with water, zinc hydroxide is formed. This zinc hydroxide further reacts with carbon dioxide to produce a thin layer of zinc carbonate. This zinc carbonate will then adhere to the zinc coating for better corrosion protection. Zinc carbonate is resilient, chemically stable, adheres firmly to metal surfaces, and acts as a protective barrier, preventing air and moisture from contacting the underlying substrate and preventing further corrosion and deterioration.

What is a Zinc Galvanizing Spray?

Zinc galvanizing spray is a sprayable, fast-curing zinc powder anticorrosive primer in an aerosol. It forms a fast-drying, adherent protective layer to repair damaged galvanic surfaces and to protect the entire exhaust system. The application of zinc galvanizing spray can be carried out in the galvanizer’s plant or on the job site. Zinc galvanizing spray is used as an anti-rust and anti-corrosion protection for iron and steel surfaces, especially at welding seams. It can be used as a coating for welding joints and drilling holes, as a conductive intermediate layer for spot welding and wherever metal must be protected from corrosion. Zinc galvanizing spray is also used in steel structure engineering, equipment, machinery, ships and appliances manufacturing.

Why is Zinc Used in Galvanizing Spray?

Zinc is used as a sacrificial agent to protect metals (steel and iron) from corrosion. This is because zinc is more susceptible to oxidation and acid corrosion than steel, so zinc takes the brunt of the damage rather than steel. The zinc layer sacrifices itself and provides anodic protection to the surface of the metal (steel or iron) exposed to the atmosphere due to scratches. Zinc will corrode first, so any damaging acid will be stopped before it can corrode the underlying steel. Zinc has therefore become an important element in galvanized structures today, protecting them from long-term corrosive damage and extending their service life considerably.

Why Zinc and not Copper?

Galvanizing spray uses zinc because it costs less than copper and is more cost-effective. In addition, zinc does not react with other metals as readily as copper, so there is less surface discoloration after zinc galvanizing. Another advantage is that zinc provides better corrosion protection than copper, making it a more reliable choice in some situations. This makes zinc galvanizing spray especially useful in areas where salt water or severe weather can cause damage to metal objects.
