What Is Powder Coat?
In the late 1960s a process was developed whereby all the ingredients of paint e.g. resins, curing agents, pigments for colour, flowing agents, were ground together into a very fine powder. The powder was then sprayed through a gun, which charged each grain with an electrostatic charge, and directed at an earthed work piece. This covered the article in a layer of powder paint, which was then baked in an oven so it melted and formed a smooth flow-out coat. This process was named powder coating.
How We Powder Coat
We grit blast etch to create a clean surface to provide good adhesion. We then apply a two pack zinc chrome-mate etch primer. This provides an extra barrier against corrosion. The parts are preheated to 200C then architectural or qualicoat powder of the desired colour is applied and the parts are returned to the oven to bake to fully cure.
