What is Powder Coating
Powder coating looks like paint. It's tougher paint. It protects metal.
It's durable, scratch resistant and make metal more attractive.
Powder coating is applied dry. The resin pigment is applied to the metal
witch is under an electrical charge.
Powder coating is a type of dry coating, which is
applied as a free-flowing, dry powder. The main difference between a
conventional liquid paint and a powder coating is that the powder coating
does not require a solvent to keep the binder and filler parts in a liquid
suspension form. The coating is typically applied electro statically and
is then cured under heat to allow it to flow and form a "skin." The powder
may be a thermoplastic or a thermo set polymer. It is usually used to
create a hard finish that is tougher than conventional paint. Powder
coating is mainly used for coating of metals, such as "white goods",
aluminum extrusions, and automobile and motorcycle parts.
There are several advantages of powder coating over conventional liquid
coatings:
Powder coatings emit zero or near zero volatile organic compounds (VOC).
Powder coatings can produce much thicker coatings than conventional liquid
coatings without running or sagging.
Powder coating overspray can be recycled and thus it is possible to
achieve nearly 100% use of the coating.
Powder coating production lines produce less hazardous waste than
conventional liquid coatings.
Capital equipment and operating costs for a powder line are generally less
than for conventional liquid lines.
Powder coated items generally have fewer appearance differences between
horizontally coated surfaces and vertically coated surfaces than liquid
coated items.
A wide range of specialty effects is easily accomplished which would be
impossible to achieve with other coating processes.
