To produce a high quality sign. Powder coating is best way in coloring aluminum products. There are major reasons for considering powder coating over liquid paint: to reduce VOC emissions, to produce better coatings with improved corrosion protection, and to reduce production costs. 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.
