What is Powder Coating?
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.
Where is Powder Coating Used?
Thousands of products and parts are currently powder coated:
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.
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.
The architectural and building market powder coats aluminum extrusions used on frames for windows and doors and modular
furniture. Many highway and building projects use powder coating on light poles, guard rails, signs, posts, and fencing.
There are also innumerable everyday uses for powder coating 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, barbeque grills, patio furniture,
garden tools, electronic components, bathroom scales, tool boxes, and fire extinguishers which benefit from a powder coated finish.
