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 a liquid suspension form. The coating is typically applied electrostatically 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. Powder coating is mainly used for coating of metals, such as ';whiteware';, aluminium extrusions, and automobile and bicycle parts. Newer technologies allow other materials, such as MDF (medium-density fibreboard), to be powder coated using different methods.

The powder coat is holding up better than a simply painted (sprayed) coating. The lower out gassing is an added/wanted benefit.
We chose:
Epoxy - hard - chemical resistant - excellent corrosion protection.
Color: white - it's medical - looks better - looks cleaner.
Smooth texture - requirement to stay clean and easy to wipe down.
We used DuPont ELW505S9
