Abstract Painting is now Powder Coating
Powder Coating and the 5 E’s to remember
Powder coating may have gotten its start as a superior finish for metal products. In fact, powder coated products are everywhere – in your home, office, shopping malls, automobile and SUV’s, stadium and playgrounds and in countless architectural applications. Regardless of the product or use, you can always count on powder coating to deliver a superior finish with the 5 E’s always in mind:
- Energy Savings
- Excellence of Finish
- Environmental Compliance
Utilizing the strenght of powder coating’s efficiency and economy, the exhaust required in powder coating ovens is lower and therefore helps reduce energy consumption. While ovens that cure sovent-based coatings must heat and exhaust huge volumes of air to protect against potentially explosive fumes, the exhaust volume of a powder coating oven is lower and more manageable. So much so that the air is re-usable and recycled into the work place
With powder coating as the finishing process there are no runs, drips, or sags. Since no drying time is required, a powder coating production line will move more efficiently than a standard paint line. More parts are able to be coated automatically, too, with significantly lower reject rates. And, with the use of appropriate application equipment, materials, and recovery methods, there is a 85% to 90% transfer rate.
In addition to its efficiency, powder coating offers a simplified line process that allows for minimum operator training and supervision. Parts can be put onto racks close together and be coated more quickly, allowing for lower per unit cost – which means greater economy. Powder coating also offers easier compliance with federal and state regulations, increasing cost – effective savings.
Excellence of Finish
Above all else, powder coating’s efficiency, economy, energy savings and environmental friendliness produce an excellence and superiority of finish that customers will come to know and count on. With its two application types (Thermoplastic and Thermosetting), powder coating offers a wide range of both extreme and decorative performance properties. Color selection is virtually unlimited, and is available in both low and high gloss.
Powder coating’s efficiency, economy, and energy savings works for the environment as well as this process eliminates VOCs – meaning the air is environmentally safer. Installation, expansion and running of powder coating operation is significantly simplified, creating the potential to place a powder coating finish operation in areas where other production systems would not be permitted. The employees also love powder coating’s reduced housekeeping problems and minimum contamination of clothing, since dry powder does not emit the kinds of fumes liquid paints do.
Powder Coating vs. Liquid Coating
Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form.
The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a “skin.” The powder may be a themoplastic or a thernoset polymer. It is usually used to creat a hard finish that is tougher than a conventional liquid paint.
There Are several advantages of Powder Coating over Conventional Liquid Coatings:
1. Powder coatings emit zero or near zero volatile organic compounds ( VOC ).
2. Powder coatings can produce much thicker coatings than conventional liquid coatings without running or sagging.
3. Paowder coating overspray can be recycled and thus it is possible to achieve nearly 100% use of the coating.
4. Powder coating production lines produce less hazardous waste than conventional liquid coatings.
5. Powder coated items generally have fewer appearance differences between horizontally coated surfaces and vertically coated surfaces than liquid coated items.
6. A wide range of specialty effects is easily accomplished which would be impossible to achieve with other coating processes.
