The photos above show a number of products that are given a powder coating. Among other things, the panel for our analog TRC 472 flight simulators are provided with a layer of powder coating and also the parts for the flight stick. But the photos also show the front of a new product. But more about that later.
Powder coating is a type of coating that 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 coating and is then cured under heat to allow it to flow and form a “skin”. The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint.
