Aluwedo® Nano PVDF aluminum composite panels uses a new and exciting technology to change the molecular structure of the surface of the paint.This improves and enhances the paint coating by giving it a longer color and gloss retention. It is applied as a 4th layer of coating over and above the 3rd layer of PVDF coating. The 4th layer of Nano coating which is made from a water soluble chemical seals any air gaps between the tiny paint molecules thus preventing dirt, water, permanent paint or any foreign particles to penetrate through the paint surface, making the paint surface lipophobic and hydrophobic.           Raw Material High strength aluminum alloy A1100, A3003, A5052 LDPE core  Surface coating: NANO PVDF coating, Dupont Adhesive film         Panel Specifications and Dimension Thickness:3-6mm, Recommended: 4mm Width: 1000-2000mm, Recommended: 1220mm, 1250mm, 1500mm, 2000mm Panel length: up to 5800mm or others as required Aluminum thickness: 0.3~0.5mm *Custom width and length available upon request  subject to minimum quantities Testing Item Standard Result Unit Weight ASTM D792 T 4mm=5.5kg/m2 Thermal Expansion ASTM D696 24-28 Thermal Deformation Temperature ASTM D648 115℃ Thermal Conduction ASTM D976 0.102kcal/m.hr℃ Flexural Rigidity ASTM D393 14.0*10^5 Impact Resistance ASTM D732 1.64kgf Adhesive Strangth ASTM D903 0.77kg/mm Flexural Elasticity ASTM D790 4030kg/mm2 Shear Resistance ASTM D732 2.7kgf/mm2 Fire Propagation ASTM E84 Qualified Wind-Pressure Resistant ASTM E330 Passed Properties Against Water ASTM E331 Passed
