United Powder Coating Limited – Powder Coating and Shot Blasting specialist in Wimborne and Dorset


Use of an electrostatic gun for spraying powder is the usual process of powder coating used at United Powder Coating. The powder inside a spray gun develops a positive charge while the metallic surface to be powdered remains grounded. Compressed air sprayed at high speed helps formation of electrostatic charge between the powder particles and metal surface.

The nozzle used for spraying depends on the shape of the surface to be powder coated. Thin substrates are coated and then stoved in the oven for 10 minutes. On cooling this film becomes hard and durable.
