Powder coating has three stages:

 

Stage I – washing

At the first stage of the powder coating process, the coated elements are washed in a special chamber.

 

Stage II – coating

The powder coating process consists in applying powder coating to a metal object by means of electrostatic or electrokinetic spraying.

 

Powder coating is applied directly to the surface, without the use of primers. Its average granulation is 10 to 100 µm. Ink is supplied by means of compressed air, which is also used to fluidise the powder.

 

Powder fluidisation is a process in which a granular material is converted to a fluid-like state. Powder particles suspended in the fluid form a mixture which can be transferred easily in pneumatic installations. The spraying powder has dielectric properties. Powder particles easily store electrical charge and are able to carry it.

 

Therefore, coated elements must be electrically conductive (surface conductivity is sufficient).

 

The charged powder particles adhere evenly to the surface of the object. This is why layers achieved by means of powder coating give smooth surfaces, without stains and wrinkles.

 

Stage III – burning off

The powder is cured in a high-temperature oven (approx. 200 °C). At this stage, very durable and evenly coated elements are achieved.
