Metallic coating:

Metallic substrates need the painting more for protection than for decorative values. Various metal types we come across in daily life are

Mild steel and iron.

They tend to corrode quickly in the presence of Moisture or other corrosive environments. Once rusting starts, it further accelerates the rusting process. Rust begets more rust.

We need to apply special paints that either passivate the steel layer (zinc phosphate or Zinc Chromate), cause negative current to suppress corrosion current (Aluminium or Zinc coating), or dissociate the metal from the environment (Epoxy and PU topcoats).

To get a higher degree of corrosion protection from the coating, blasting the surface with sand/metal shot gives the best result; however, wherever blasting is not possible, surface-tolerant Epoxies are available.

Mazon does various high-performance industrial coatings on steel structures, including post-sand blasting; at painting yards, it is also capable of applying surface tolerant Epoxy by doing a power tool cleaning, followed by Polyurethane Topcoat.

A cost-effective coating solution for iron substrates is Zinc chromate red oxide primer, followed by alkyd-based enamel paint.

Stainless Steel and non-Ferrous metals like aluminium, galvanised iron, copper, etc. These surfaces are difficult to coat and need special treatment or a special primer. The Mazon team can recommend and apply the required coating system for such substrates.

Few coating systems for metal are as mentioned below-
