Powder coating

Our powder coating line provides attractive finish and corrosion protection for metal products. In addition to this powder coating technology has a number of advantages over conventional painting:

  • Powder coatings emit zero or close to zero volatile organic compounds (VOCs).
  • They are more resistant and last longer than conventional painting, no dripping or layering.
  • Powder coating production lines produce less hazardous waste than conventional liquid coatings.
  • Powder coated elements have less differences in their appearance between horizontally or vertically painted surfaces compared to liquid painted elements .
  • Another advantage is the productivity – since minimum manual labor is required, plus it saves time for drying.

Powder coating process includes three basic steps:


Before applying the powder coating it is essential to remove oils, dirt, grime, lubricating grease, metal oxides, etc.


Powder coating is applied to metal objects by spraying the powder using an electrostatic gun, or corona gun. The gun imparts a negative electric charge to the powder, which is then sprayed by mechanical or compressed air spraying and then accelerated toward the workpiece by the powerful electrostatic charge.


When a thermoset powder is exposed to elevated temperature, it begins to melt, flows out, and then chemically reacts to form a higher molecular weight polymer in a network-like structure.
