Powder coating is a finish that looks like paint, but is applied as a dry powder. The coating is typically applied with a spray gun electrostatically and is then cured under heat to allow it to flow and form a "skin". It is mainly used for coating of metals found in thousands of products from industrial machinery to household items.
Because powder coating does not use a liquid carrier, it can produce thicker coatings than conventional paints without running. As well, because no carrier fluid evaporates away, the coating process emits few volatile organic compounds. Finally, several powder colors can be applied before curing them all together, allowing color blending and special bleed effects in a single layer.
The powder creates a hard finish that is tougher than conventional paints can offer, while still providing an attractive finish. Powder coated products are more resistant to scratches, corrosion, fading from sunlight, and extreme weather. It's a tough one coat metal finish. Looks great. And lasts a long, long time. In addition to being durable, powder coating is environmentally friendly with virtually no emissions, no solvents and no hazardous waste.
