Powder coating


Powder coating – consists in applying electrified particles (20-100 μm) of powder paint onto a conductive surface, e.g. metal. A powder coat stays on a surface of the detail painted due to electrostatic forces.

Powder coating is performed by two basic electrification and powder paint application methods:

  • Electrostatic spray – high voltage method 40-100 kV, commonly known as “crown”,
  • Electro-kinetic spray – tribo-electrisation method, friction type, called “tribo”.

Then, elements covered with paint are heated to 140-200°C and consequently powder gets melted and polymerised. The obtained paint coat is resistant to corrosion, chemicals, high temperature and mechanical damage.
