Powder Coating
Powder coating is the application of a dry, powdered coating on the surface of your parts. The parts are given an electrostatic charge and the powder is given the opposite electrostatic charge. This ensures complete coverage when the powder is sprayed – even on complex shapes.

The Diamond Metal Finishing Company is a leading processor of aluminium chromate and non-chromate conversion coatings. Aluminium chromate conversion coatings improve the corrosion resistance of wrought, heat treatable, cast and sheet aluminium alloys whilst providing an excellent base for wet paint or powder coating or can be used as a standalone finish.
