Powder paint is sprayed on the cleaned metal product. During spraying, powder paint particles are electrically charged from an external source or electrified by friction. The electric field transfers the powder paint particles to the painted product, which has the opposite charge. Powder paint particles that have not settled on the product are trapped in the spray booth and can be used for re-spraying, which is not possible with conventional liquid paints. Then the product with the applied powder paint is transferred to the polymerization chamber to "bake" the paint.

In the process of forming a coating from the applied powder layer, a monolithic high-quality coating is created on the surface of the product.

The process of forming a coating is carried out by heating a layer of powder paint until it melts with the formation of a monolithic layer. During subsequent processing, hardening (for thermosetting materials) or cooling (for thermoplastic materials) of the layer forms a hard film.

The melting of powder paints is divided into three stages: the powder is melted and turns into a viscous-flowing state; a monolithic layer of fused powder particles is formed; the surface to be painted is wetted by the molten polymer to form a coating.
