Architectural powder coatings are high performance, high quality, durable coatings designed to offer excellent durability, good chemical resistance and mechanical performance. Just like with liquid PVDF finishes, powder coatings come with a limited warranty when they are applied to architectural grade aluminium. Whilst guarantees can vary depending on the project location, powder specification and powder manufacturer, our coating warranties cover will always centre around gloss level, colour retention and adhesion.
