Whether you’re new to powder coatings or an experienced pro, you’re
probably well aware that powder coating is a fantastic painting
method that creates a tough, durable and beautiful finish. No
matter whether you’re using a single gun and small oven or a large
fully automated line, the process is basically the same. A powder
spray gun is used, which when triggered gives an electrostatic
charge to the powder particles passing through it. As the parts to
be coated are grounded, the powder is attracted towards the part
via the electrostatic process. Once the powder is applied the parts
are cured in an oven, which melts and cross-links the powder over
the surface of the part and creates a tough, scratch resistant and
beautiful finish.

Powder Application Systems
In addition to spray application with electrostatic guns, powder
coating materials can be applied by a dip method called fluidized
bed. Fluidized-bed powder coating was developed by Edwin Gemmer for
application of thermoplastic resins and patented in 1953.
In fluidized-bed coating, parts are preheated to 450–500°F and then
dipped into a tank filled with powder material that has been
“fluidized” by addition of compressed air through a porous membrane
at the bottom of the tank. In some cases, the powder is
electrostatically charged.
Another option is flame-spray application. In flame-spray, which is
used to apply thermoplastic powder materials, powder is propelled
through the flame in a heat gun using compressed air. The heat of
the flame melts the powder, eliminating the need for ovens.
Yet another method of application is called hot flocking. In this
process, the part to be coated is preheated so that the sprayed
powder will gel when it comes in contact with the hot part surface.
Hot flocking is often used for functional epoxy applications
because it builds a thick film that will provide exceptional
performance. These fusion-bond epoxy (FBE) products are often used
to coat valves and pipe used in extreme conditions such as oilfield
or offshore applications.
