With an unrivalled reputation for quality, reliability and professionalism, Powdertech has become the "go-to" firm for British and international architects who are looking for striking, weather-resistant powder coating finishes that will stand the test of time and create a memorable finish for their buildings. 

Powdertech are architectural metalwork powder coating applicators with our own unique brands and a philosophy of support throughout the construction process to deliver what is specified.

Powder Coating is the application of organic powder by electrostatic attraction to metal. Once cured by heat the finish is an even and continuous, hard skin. All processes are factory applied under controlled, stable conditions. This provides significant benefits over traditional wet spray painting.

Up to 70% of wet paint is solvent to keep the binder and filler parts of the coating in liquid suspension. It is these solvents that cause many of the environmental problems for wet paints as they contain pollutants in the form of volatile organic compounds amongst other substances. Sprayed wet paints can travel long distances even in mildly windy conditions and the chemicals will affect plants, people, animals and building surfaces. Paint residues on the ground can enter the water system and can also cause marine, river and lake contamination.

Powder coatings are dry powders and free of such substances. Any waste material is inert though there is little waste as the process takes place in a sealed booth. Any powder that is over sprayed and doesn’t adhere to the surface, is collected, filtered and re-used. The powder efficiency of the process can reach over 95%.

Wet paint spray curing depends on atmospheric conditions and curing between successive coats. Powder coating is a one-coat system, cured in controlled conditions and over known time. Wet paint may need several layers applied over days whereas powder is one layer cured in 20 minutes.
