ALUSONG NANO coated aluminum composite panels are produced by a new and exciting NANO PAINT technology. A transparent NANO coat is applied over 2 or 3 PVDF coating to enhance the performance of the coated panels weatherability and durability resulting in longer color and glossy retention. The NANO coating prevents dirt, water, permanent spray paint, carbon monoxide, grease, oil or any foreign particles to penetrate through the paint surface. In addition, the NANO coating is a non-toxic, VOC EMISSION FREE coating system, which makes the surface self –cleaning and repellent to air-borne pollutants.
