Sun selected Powder Coating as our exterior finish of choice for our aluminum clad windows and doors because of its outstanding weather ability, film toughness, extensive range of colors, and its low environmental impact.
Our powder coated aluminum extrusions have a thick, hard finish which is tougher than conventional painted finishes. They have a long finish life with excellent resistance to chipping, cracking, peeling and fading.
Our standard finish meets AAMA 2604 requirements and allows us to provide a 20 year finish warranty. An optional AAMA 2605 finish is also available and offers a 30 year finish warranty.
Powder Coating is basically paint in powder form. This dry pigment powder is applied to an aluminum extrusion that has been prepared in a multi-stage cleaning process. A negative electrical charge is applied to the extrusion and as the powder is sprayed, the negative charge attracts and holds the positively charged powder in place. The coated extrusion is then heated in an oven that bakes on the finish. The extrusion is removed from the oven, allowed to cool and (after inspection) is sent on for product production. The coated extrusions now have a hard finish which is tougher than conventional painted finishes. Powder coated surfaces have a long life and are resistant to chipping, cracking, peeling and fading. Powder Coating is also very environmentally friendly, with virtually no VOCs and no lead or chromium in any of the processes.
