Powder coating is an advanced method of applying a decorative and protective finish to a wide range of materials and products that are used by both industries and consumers. The powder used for the process is a mixture of finely ground particles of pigment and resin, which is sprayed onto a surface to be coated. The charged powder particles adhere to the electrically grounded surfaces until heated and fused into a smooth coating in a curing oven. The result is a uniform, durable, high-quality, and attractive finish. Powder coating is the fastest-growing finishing technology in North America, representing over 10% of all industrial finishing applications. Powder is somewhat like a finely ground plastic - a mixture of resin and pigment. The general idea is to cover the metal part with this powder, and then heat it briefly in an oven so that the powder melts and flows around it, forming a solid protective layer over the part. Electrostatic spray is the most common and versatile application method for powder coating. Powder is supplied through a delivery hose and spray gun, and is conveyed by clean, dry, oil-free air. The power is charged by the spray gun's electrode and, when directed at a conductive, grounded surface, is deposited and held to that surface by static charge. Powder is offered in a variety of colors (RAL and other standards), textures and patterns by a wide variety of powder suppliers. RAL is a European color chart (the most standard color spectrum for powder) that puts a number to a color. The only negative side of powder coating is the limitation of custom colors at reasonable prices. Most custom colors require minimum purchases and can be very expensive. See Compliant Liquid Coating for custom color matching.

Variety of Chemistries to serve your purpose Powder coatings come in a variety of chemistries to accommodate the type of protection you need for your particular application. From polyesters to protect your parts from the suns harmful UV rays, to epoxies that give you that extra durable strength from chemicals and scratch resistance.

Epoxies:
Ideal for applications requiring ultimate corrosion resistance, excellent chemical and mechanical properties, exceptional adhesion, and the ability to meet demanding specifications. Epoxies can be custom-tailored to suit specific applications such as long-term dielectric strength at high temperatures. Not recommended for use outside.

Polyesters:
Available in TGIC and TGIC-free formulations. They are tough, attractive, and demonstrated outstanding physical properties and overbake resistance. They can withstand prolonged outdoor exposure and are often the coating of choice for lawn and garden furniture as well as other types of outdoor equipment. Polyester clear coats can be applied over a basecoat to enhance exterior performance.

Hybrids:
A blending of epoxy and polyester resins and are used primarily for indoor applications. Hybrids offer better penetration into corners and recesses (Faraday Cage Areas) and are less sensitive to overbake on curing than many other chemistries.

Polyurethanes:
Offer outstanding thin-film appearance and toughness with excellent weather ability. They are competitive with high quality liquid paints and demonstrate superior chip, mar, and scuff resistance. Their adhesion to properly prepared ferrous and non-ferrous substrates is excellent, giving them long-term resistance to humidity and salt spray. 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. Protects the Environment & Saves Money.

Powder coating is also highly protective of our environment. 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. Elimination of VOCs and reduction of wastes saves money and helps companies comply more easily and economically with the regulations of the U.S. Environmental Protection Agency. In fact, one of the major elements in expanding the market for powder coating has been the implementation over the past 30 years of stringent air pollution control legislation.

Appliances
The appliance industry benefits from powder coating on front and side panels of ranges and refrigerators, washer tops and lids, dryer drums, air-conditioner cabinets, water heaters, dishwasher racks, and cavities of microwave ovens. Powder coating has also replaced porcelain enamel on many washer and dryer parts.

Automotive.
The automotive industry uses powder coating on wheels, bumpers, hubcaps, door handles, decorative trim and accent parts, truck beds, radiators, filters, and numerous engine parts. A clean powder topcoat has been developed to protect auto bodies. BMW and Volvo are using it on their new model cars, and GM, Ford, and Chrysler have formed a consortium to test this technique on their production lines.

Architecture/Building.
Nowhere else are the benefits of architectural powder coating more evident than on the thousands of commercial, industrial, government, residential, historic and institutional buildings from around the world. For 30 years, powder coating has been the finish of choice for a superior, more colorful, longer lasting and more durable finish. Powder coating is specified because of its durability, scratch resistance, gloss retention, weather ability, resistance to chalking, the unlimited range of colors, finishes, glosses and textures, the fact that it meets AAMA specifications and because it is an environmentally friendly finishing process, making it an important part of a sustainable or green building project that incorporates low-emitting products. Virtually any part and any product in your next project might lend itself to powder coating including metal, aluminum, composites, wood, plastic, glass and ceramic. Powder coating is superior to liquid paint, anodizing, PVDF and Kynar500®.

Everyday Products.
There are also innumerable everyday uses for powder coated products such as lighting fixtures, antennas, and electrical components. Farmers have powder coated tractors and farm equipment. Fitness buffs use golf clubs and golf carts, ski poles and bindings, snowmobiles, bicycles, and exercise equipment that are powder coated. Shop owners have powder coated display racks, shelves, store fixtures, and vending machines. Office workers use metal furniture, computer cabinets, mechanical pencils and pens, thumbtacks, and other desk accessories that are powder coated. Parents have powder coated baby strollers, cribs, metal toys, and wagons. And home owners have lawn mowers, snowblowers, barbecue grills, patio furniture, garden tools, electronic components, bathroom scales, tool boxes, and fire extinguishers which benefit from a powder coated finish. There are two main types of powder available to the surface finisher:

• Thermoplastic powders that will remelt when heated, and
• Thermosetting powders that will not remelt upon reheating. During the curing process (in the oven) a chemical cross-linking reaction is triggered at the curing temperature and it is this chemical reaction which gives the powder coating many of its desirable properties.
