Powder coating

The main difference between powder coating and wet coating is the application method.

The powder coating method is based on electrostatic spray deposition. Powder coating particles are electrostatically charged onto the substrate.

The powder used in powder coating process can consist of different ingredients such as acrylic, polyester, epoxy of polyurethane. After the application the powder coated substrate is cured in a specialized oven. In temperatures of +160–200 centigrade the powder melts into a gel and coats the surface.

The substrates suitability for powder coating is often determined for example by different exposure classes. Other limiting factors can be either the size of the treated substrate or the substrates material that should be preferably of metal (ex-cluding some rare occasions).

Powder coating requires always an adequate pretreatment. Another industrial painting method is wet coating.
