What is Powder Coating?
Powder coating is a high quality finish that's found on thousands of products you come in contact with each day. It makes products durable, attractive and extremely scratch-resistant too.
How does it work? Powder coating is a dry finishing process. Finely ground particles of pigment and resin are electrostatically charged and sprayed onto the products to be coated.
The parts to be coated are positively grounded, so that the charged particles adhere to them until melted and fuse into a solid coating in a curing oven.
The result: a sleek, strong, high-quality finish.
The powder coating process itself offers another advantage - it is environmentally friendly and virtually pollution-free! Unlike liquid paint, no solvents are used in powder coating, so only negligible amounts of VOC’s are released into the air. In addition, unused or over-sprayed powder can be recovered, so any waste is minimal and can be disposed of easily and safely.

Protect the environment & Save Cost
In addition to being the more durable and attractive choice, powder coating is also highly protective of our environment.
While liquid finishes contain solvents which have pollutants known as volatile organic compounds, or VOC’s, powder coating contains no solvents and releases negligible amounts of, if any, VOC’s into the atmosphere. Thus, there is no longer a need for finishers to buy costly pollution control equipment, and companies can comply more easily and economically with the regulations of the U.S. Environmental Protection Agency.
Powder coating is a clean process, allowing exhaust air from the coating booth to be returned to the plant, and less oven air is exhausted to the outside. In fact, one of the major elements in expanding the market for powder coating has been the implementation of stringent air pollution control legislation over the past 30 years.
In addition, up to 98% of 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. This reduction of wastes saves companies money on waste disposal equipment.

Benefits for Consumer
The benefits of powder coating for consumers are simple: powder coating will make your purchase look better and last longer – not to mention its reduced environmental footprint!
Powder coating is already found on thousands of products that you come in contact with everyday. From bulldozers and chainsaws to your coffee machine and child’s crib, powder coating protects the roughest, toughest machinery as well as the household parts that you depend on daily.
The result of choosing a powder coated product is that it will have the most attractive, durable, high-quality finish available.

Benefits for Industry Users
Powder coating provides a durable and high-quality finish, with a wide range of performance properties including excellent resistance to impact, abrasion, heat, stains, extreme weather and fading from sunlight. Texture selections range from smooth surfaces to a wrinkled or matte finish. Rough textures are also available, designed specifically for hiding any surface imperfections. And color selection is virtually unlimited, including clear coats.
Powder coating is the smart choice to run the most economical and efficient operation:
Powder coating is the smart choice to run the most economical and efficient operation:
- Lower heating costs for curing oven - The exhaust requirements for a powder coating oven are lower than solvent-based coatings, resulting in energy savings.
- Greater operating efficiency/lower unit costs - No drying or flash-off time is required. Parts can be racked closer together on conveyors and pass more quickly through the production line.
- Lower reject rates - More parts can be coated automatically with fewer rejects because powder coating does not run, drip or sag.
- High utilization efficiency - With proper application equipment, powder materials and efficient recovery methods, one-coat application and 95%-98% powder utilization efficiency are readily available. If more than one color is desired, color changes can be made quickly.
- Lower personnel costs - Minimal operator training and supervision are required for a powder line. Employees prefer working with dry powder because of lack of fumes, reduced housekeeping problems and minimum clothing contamination.
- Simplified permit process - The permitting process for a powder coating operation is simpler. Compliance with federal and state regulations is also easier, saving both time and money.
- Negligible VOCs - Powder coatings contain no solvents and therefore emit negligible, if any, polluting VOCs into the atmosphere.
- Less exhaust - Powder coating is a clean process, allowing exhaust air from the coating booth to be returned to the plant, and less oven air is exhausted to the outside.
- Reusable overspray - Up to 98% of powder overspray can be retrieved and reused.
- No costly waste disposal equipment - Unused powder can be reclaimed and returned to a hopper for recirculating through the system, with negligible waste.
