China PVDF Coated ACP for Cladding

NEITABOND PVDF coated ACP for claddingNEITABOND PVDF aluminum composite panel consists of two layers of aluminum skin sandwiching a PE core in a continuous extrusion process. The outer surface of panel is coated with PVDF Kynar500 fluorocarbon coating to provide a long lasting, durable finish for wall cladding applications.
1.Colours and Surfaces
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 nanometer 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.
