What is powder coating, and how does it work?
Powder coating is a method of applying a finish to a wide range of materials for both industrial and consumer use.
Powder coating is a dry finishing process. Finely ground particles of pigment and resin are electrostatically charged and then sprayed onto the item to be coated.
The item to be coated is electrically grounded, so that the charged powder particles adhere to the item until heated which cause them to “gel” into a smooth, consistent and uniform coating.
The end result is an attractive, durable, high-quality finish. The powder coating process itself offers another advantage over traditional solvent-based wet paint systems — it’s environmentally friendly & virtually pollution-free!
Unlike liquid paint, no solvents are used, so only negligible amounts of VOCs are released into the air. In addition, unused or oversprayed powder can be recovered, so waste is minimal and can be disposed of easily and safely.
So what are the main advantages over solvent based painting systems?
– It’s More Durable
Powder coating gives consumers, businesses, and industry one of the most economical, longest-lasting, and most color-durable quality finishes available.
Powder coated surfaces are more resistant to chipping, scratching, fading, and wearing than other finishes. Color selection is virtually unlimited with high and low gloss, metallic, and clear finishes available. And colors stay bright and vibrant longer. Texture selections range from smooth surfaces to a wrinkled or matte finish, and rough textures designed for hiding surface imperfections.
– It’s Environmentally Friendly
While liquid finishes contain solvents which have pollutants known as volatile organic compounds (VOCs), powder coating contains no solvents and releases negligible amounts, if any, of VOCs into the atmosphere. Thus, there is no longer a need for finishers to buy costly pollution control equipment. In addition, most powder coating overspray that does not adhere to the part can be retrieved and reused, virtually eliminating the waste commonly found in liquid finishing processes.
Powder Coating Myths Debunked:
“Powder does not chip” — False!
If prepared and applied correctly powder is far more chip resistant than liquid coatings. Powder can still chip if the impact is hard enough.
“Powder fades/peels after exposure to the weather” — False!
There are several different types of powder that are designed for prolonged exterior exposure(15+ years or more). These powders are used in all types of architectural applications and show superior performance over time. You must carefully select the type of powder that best fit your needs. One that has better chemical resistance would not be the best choice for exterior application. We can help you with your selection.
“Powder will lose its gloss when exposed to UV.” — False!
TGIC powders include some of the best UV resistance of any coatings. Powder (like liquid paint) can be buffed and waxed to restore it original look.
