BENEFITS OF POWDER COATING (OR THE FIVE E's)
  • Environmental Compliance

    Liquid finishing requires the use of solvents. These solvents require venting, filtering and solvent recovery systems to
    control the emission of volatile organic compounds (VOC's). But powder coating contains no solvents and therefore emits negligible, if any, polluting VOC's into the atmosphere. Exhaust air from the coating booth can be safely returned to the coating room, and less oven air is exhausted to the outside, making the powder coating process a safer and cleaner finishing alternative. And since the powder is dry, most powder coating over-spray, up to 98% of it, an be readily retrieved and reused. The waste that results is negligible, and can be disposed of easily and economically.
     
  • Energy Savings

    The absence of voc's in the powder coating process means that air used to exhaust the powder spray booth can be re-circulated directly into the plant, eliminating the cost of heating or cooling the make- up air. Heating costs are also lower for the curing oven. While ovens that cure solvent- based coatings must heat and exhaust volumes of air to ensure that the solvent fumes do not reach a potentially explosive level, the exhaust required in powder coating ovens is lower, resulting in energy savings.

  • Efficiency

    Greater operating efficiency with a powder system saves both time and money. No drying or flash- off time is required. Parts can be racked closer together on a conveyor, and pass more quickly through a production line, resulting in lower unit costs. More parts can be coated automatically, as powder coating does not run; drip or sag, and results in significantly lower reject rates. With the use of appropriate application equipment, powder materials, and efficient recovery methods, one coat application and overall powder utilization of 95% to 98% are readily available. And if more than one color is required, color changes can be accomplished in a relatively short period of time

  • Economy

    While the factors above contribute to the economical benefits of powder coating, there are additional cost savings which include minimum operator training and supervision for a powder line, simplified clean-up of the operation, and easier compliance with federal and state regulations which saves both time and money.

  • Excellence of finish

    Powder coating produce an attractive finish, which offers excellent resistance to corrosion, heat, impact, abrasion, fading from sunlight, and extreme weather. Color selection is virtually unlimited with high and low gloss, metallic, and clear finishes available.
