Product Description
Polyester coated aluminum has a uniform surface. It minimizes thicker painted areas at edges and corners or the "orange peel" texture typically associated with powder coatings. PE coatings are more cost-effective than PVDF coatings, but are less durable.
This energy-efficient coating technology bakes at low temperatures and is ideal for interior and exterior applications. In addition, it can easily coat large panels, curves and complex shapes.
Litong’s lacquered aluminium coil is suitable to be worked up in a sectional rolling and pressing processes for louvers of Exterior Horizontal Blinds.
