We have three powder coating plants, with two high capacity vertical powder coating unit, to provide finishing in the variety of colors in RAL colors. The unit is certified with Qualicoat.
Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between conventional liquid paint and 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 electrostatic ally and is then cured under heat to allow it to flow and form a "skin". The powder may be a thermoplastic or a thermoses polymer. It is usually used to create a hard finish that is tougher than conventional paint.
After application of the powder coatings, the aluminum extrusions proceed to an indirectly heated convection oven for a complete cure of the powder coatings. The natural gas fired ovens are very energy efficient in design and provide the optimum environment to cure the powder coatings. Indirectly heating the powder cure oven eliminates the concerns about possible contaminants from the burner and helps provide excellent control over the temperature profile within the oven.
