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 powder coating is then fused to the surface (cured) in a temperature-controlled oven and the powder ‘melts’ over the part to form a hard, protective coating.
Powder coatings come in a wide variety of colours and textures and offer a highly durable scratch and chemical resistant finish. It also provides excellent corrosion protection.
There are five major types of powder
- Epoxy Polyester
- Nylon (warm to touch)
Each of these powders has different performance characteristics.
We stock the full range of Pantone, RAL, BS381C and BS 4800 and colours as shown on our Colour Charts page and offer a choice of finishes including matt, gloss and satin. Non-standard colours may be available on request.

The component will firstly be thoroughly cleaned, degreased and mildly etched prior to this process commencing.
The treatment chosen is then applied by either brush or swab to localised areas or by immersion if required for the entire component. Once applied or immersed the process will take up to 5 mins to create a thin, clear or gold coloured, protective film across the component or area treated.
The component is then rinsed initially in cold clean running water for 30 seconds, followed by a hot rinse across within a weakened treatment solution for 15-30 seconds.
The technician will then make a final inspection to make sure the component or area treated has an even clear or gold coloured coating.
