FIELD: chemistry.
SUBSTANCE: method of applying comprises applying a first layer of powder coating followed by applying a second layer of powder coatings without any substantive curing of the first layer of the powder coating before applying the second layer of powder coating followed by simultaneously curing the first layer of the powder coating and a second layer of powder coating said first layer of powder coatings or powder coating the second layer comprises 1 to 10 wt % of the conductive component having a specific con rotivlenie below 5 ohm-cm for volume filling factor of ≤70%, and a film-forming polymer used in said at least two layers of two different thermosetting powder coating is one or more selected from carboxy-functional polyester resins, hydroxy-functional polyester resins, epoxy resins, functional acrylic resins and fluoropolymers.
EFFECT: method allows to obtain coating without surface defects.
