Why is powder coating superior?
Coating is an advanced method of applying a
decorative and protective finish to virtually any type
of metal that can be used both by industry and
consumers. The powder used in the process is a mixture
of finely ground particles of pigment and resin, which
is electrostatically sprayed onto the surface to be
coated. The charged powder particles adhere to the
electrically grounded surfaces until the powder is
heated and fused into a smooth coating in the 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.
Coating gives consumers, businesses, and industries
one of the most economical, longest lasting, and most
color-durable quality finishes available on virtually
any type of metal. Powder coated surfaces are more
resistant to chipping, scratching, fading, and wearing
than other finishes. Color selection is virtually
unlimited with flat, satin, gloss, high gloss, metallic,
candies, clear, iridescent, fluorescent, wrinkle, hammer
tone, and glitter finishes available. Colors stay bright
and vibrant longer. Texture selections range from smooth
surfaces to wrinkled or matte finishes, and rough
textures designed for hiding surface imperfections.
It protects the environment
Coating is also highly protective of our
environment. While liquid finishes contain solvents
which have pollutants known as volatile organic
compounds (VOC's), powder coating contains no solvents
and release negligible amounts, if any, VOC's into the
atmosphere. Therefore, there is no longer a need for
finishers to buy and maintain costly pollution control
of VOC's and the reduction of waste saves money and
helps companies comply more easily and economically with
the regulations of the U.S. Department of Environmental
Protection Agency. 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 thirty years.
Where is Powder Coating used?
Thousands of products and parts are
currently powder coated:
- 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 clear 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 - The
architectural and building market powder coats aluminum extrusions used on
frames for windows and doors and modular furniture. Many highways and
building projects use powder coating on light poles, guardrails, signs,
posts, and fencing.
- Everyday Products - There are
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, all
of which 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. Homeowners have
lawn mowers, snow blowers, barbecue grills, patio furniture, garden tools,
electronic components, bathroom scales, toolboxes, and fire extinguishers.
These items all benefit from a powder coated finish.
