ALUSONG PVDF aluminum composite panel is exclusively made for exterior wall cladding, its excellent property comes from the front coating and its outstanding durability, PVDF kynar 500 coating is achieved through the continuing roller coating system which is based on the most prestigious technology and the multiple layers are individually stoved at 220-260℃, the two cover sheets sandwich the same mineral core of polyethylene which is Hardly inflammable. Chemical salt and alkali resistance for 20 years
PVDF coating, made of fluorine carbon resin, is solidified to dry film with super weather resistance. We have normal PVDF and NANO PVDF coatings. Normal PVDF coating, certified as KYNAR 500, is made of 2-3 time coating and baking, has good properties of anti-acid, Anti-alkali, is durable in atrocious weather and environment. Warranty could reach to 15 years for exterior use. NANO PVDF coating, with self-cleaning NANO meter paint on the normal PVDF coating, is used to protect the surface from pollution, dust or dirty rains. Warranty could be up to 15 years for exterior use.
