For Steel:
All surfaces must be dry, clean and free from contaminators. It is suggested a good substrate cleaning as required (sand blasting – degreasing – phosphatizing or chromed, etc…).
For Aluminum:
In order to obtain optimal anti-corrosion properties, it is advised to apply a chemical pretreatment prior to powder coating application.

Applied by electrostatic corona spraying using classic devices which can provide a negative tension of 60-80 kV. The powder is cured in a suitable convection or combustion, or induction, etc…
