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". (source: Wikipedia). Powder coating therefore has no VOCs and is 100% non-toxic. Powder coating, as well as adding a protective layer that avoids natural occurring rust, allows for an unlimited variety of colours. Architects and design professionals love this feature!
