Powder coating is a dry clean finish that gives a highly durable coating. In the long run, powder
coating will save you money, time and the need to use volatile organic compounds.
Powder coating has been increasingly accepted as the preferred industrial finishing process.
The reasons for this use of powder coating can be attributed to three major forces:
ECONOMY
1) 96% of the powder coatings applied can be applied to the part being coated.
2) Powder coating is not an industrial pollutant.
3) Powder coating is recognized by the industrial sector, as the most cost effective means of
corrosion control.
EXCELLENCE
1) The cured powder finish is less susceptible to damage than a liquid finish.
2) A range of powders such as epoxy provides coating flexibility.
3) Polyester powders provide additional advantages in ultraviolet and weathering resistance.
ECOLOGY
1) Stringent regulations are being aggressively enforced in an effort to control air
pollution and hazardous waste disposal. Powder coating is the overwhelming preference of the
EPA.
2) Powder coating eliminates solvent fumes and VOC's from the coating
process.
3) There is no hazardous waste associated with powder coatings.
WHAT IS POWDER COATING?
Powder is a dry pigment which is thermally fused or melted to the surface to be protected. Instead
of disolving the coating pigment in a solvent for painting or spraying, Fusion Bonded Powder is
applied in a granular form. There are many types of powder, although epoxy is the industrial
favorite, the particular conditions to which a part will be exposed will determine the kind of
powder such as Polyester, Kynar,Teflon, or TGIC to be used. More than one type of powder may be
used on a single part and virtually any color is now available.
HOW IS THE POWDER APPLIED?
The application process involves applying a charge to the dry powder particles and spraying them
onto a grounded substrate. The substrate, or part, is typically grounded through the conveyor or
hanger holding the part. The powder, once attracted to the part, is then held on the surface until
it is melted and cured into a smooth corrosion, impact, and chemically resistant
coating.
