Powder coating is applied to suitably prepared metal as a free-flowing, dry powder which is then ‘cured’ at high temperatures.

Once the metal is thoroughly cleaned, it is electrostatically charged before being sprayed with a thermoplastic or a thermoset polymer powder, with the curing process forming a tough outer ‘skin’.

It is a one coat application process, with the finished item being ready immediately after curing, rather than having to wait for the colour to dry or have subsequent lacquers applied.

It is a solvent-free process, minimal air pollution and with a material loss of under 1%, it is very environmentally friendly.

Powder coating delivers consistently high quality with the a finish which is durable and offers great protection for the metal underneath.

In 2017, CN Metalworks invested in a new Aquaex 7.5m x 3.5m powder-coating line from leading UK manufacturer RDM Engineering, featuring the unique water wash extraction system.

The Aquaex unit is designed to remove any fumes, paint or powder, ensuring clean and safe working conditions along with water scrubbing tower to prevent particles being exhausted into the atmosphere.

Powder coating is available in a huge range of colour options and CN Metalworks are able to offer the complete spectrum of RAL colours for you to choose from.

Should you require a bespoke colour, please contact us and we shall endeavour to match as closely as possible.

Powder coating creates a hard finish that is typically tougher than conventional liquid paint.

Industrial powder coatings contain no solvents or chemical carriers like traditional wet-paint systems and only release negligible amounts of Volatile Organic Compounds (VOC) into the atmosphere, so is seen as a more environmentally friendly application.

Unlike conventional liquid spraying, powder coatings can produce much thicker coatings without the colour running.
