POWDER COATING
THE POWDER COATING PROCESS
​
Powder Coating is a dry-paint process using, as the name implies, a powdered form of paint. The powdered paint is electro-statically charged by a special spray gun which causes the paint to stick to the part. The painted part is then heated in an oven, melting the paint powder and fixing it to the surface.
​
The process is simple and reliable, producing a high quality finish. Due to the attraction between the paint and the part, the paint particles are actively drawn to the target areas, even covering edges that face away from the spray direction. This gives an even, high quality finish.
​
Powder Coating can be used on a variety of materials and is available in a wide range of colours, gloss levels and other types of finish.
FEATURES & BENEFITS
​
Powder Coating produces a finish that is relatively hard, abrasion resistant and tough. Whilst the paint is not chemically bonded to the material, when correctly prepared and applied, it will provide a long life. It is a highly cost effective, producing a paint finish that will not crack, chip or peel.
​
Powder Coating is available in a wide range of finishes and colours to suit most requirements.
