Powder coating is a process which uses paint powder
without solubles. The powder is applied to all metallic surfaces by
means of spray guns which charge the powder with a voltage of approx.
90,000 V. The parts to be coated must be earthed to assure a proper
electrostatic adhesion of the powder.
The paint is cured at a temperature of approx. 180°C.
Therefore the dimensions of the parts to be coated are limited by the
opening and length of the curing oven.
Prior to coating the parts must be cleaned of oil,
grease, dirt and all other contaminations. This is done by a high pressure
spray cleaning unit.
It is the combination of surface preparation and coating
which assures the quality expected by the client.
