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 is a mixture if
finely ground particles, which is sprayed onto the surface to be coated. The
charge particles adhere to the electrically ground surface until heated and
fused into a smooth coating in a baking oven.The result is a uniform, durable
high quality and attractive finish.
Environmental Compliance
Liquid finishing requires the use of solvents. These 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.
Energy Savings
The absence of VOC’s in the Powder Coating process means that air used to
exhaust the powder spray booth can be recirculated directly into the plant,
eliminating the cost of heating or cooling the make-up air. Heating costs are
also lower for the baking oven. While ovens that cure solvent-based coatings
must heat and exhaust huge volumes of air to ensure that the solvent fumes do
not reach potentially explosive levels, the exhaust required in Powder Coating
ovens is lower, resulting in energy savings.
Efficiency
Greater operating efficiency with a Powder system save both time & money. No
drying or flash-off time is required. Parts can be racked closer together on a
line 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 0r 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 efficiency of 95%
to 98% are readily available. And if more than one Colour is Required, Colour
changes can be accomplished in a short spare of time.
Long term lay-by available but all Xmas Orders to be finished by mid nov.
