Powder coating is the application of dry powder paint particles to a part, mainly used for coating metals. The dry powder is temporarily attracted to the part by means of an opposite, low voltage electrical charge. The powder, now covering the part, is then heated until it ‘melts’ and flows evenly around the part forming a plastic-like skin. A chemical reaction amongst the particles called cross-linking also occurs, which produces long molecular chains ensuring durability.

Efficiency is core to our service offering.
Traditional ‘wet’ painting techniques such as spray-painting or even household paints require the paint to be dispersed along with a suspension liquid carrier. The carrier allows the paint to be spread evenly, although this is not a guarantee and the liquid carrier must evaporate in order for the wet paint to dry.
