Abstract

The coating method involves mixing with air a paint in the form of a powder consisting of a number of particles dispersed in air. The individual particles forming the powder paint are electrostatically charged by submitting the paint to an electric ionisation field. The electrostatically charged powdered paint is projected against a workpiece (11) at the same time as the air is ejected through a spraying nozzle (10). The air to be conveyed to the spraying nozzle is enriched with at least one additive gaseous fluid having a greater electric conductivity than the air itself, so that the electrostatic charge induced on the paint particles by effect of the electric ionisation field is increased.
