Aluminum Coated Coil
PVDF coated Aluminium coil
we produce the PVDF coated aluminium coil with advanced equipment and technology. The continuous rollers painting can avoid colors difference. In 240 celsius degree baking chamber, the PVDF paint can creat a pyknotic high performance protective layer on the aluminium surface to prevent corrosion and pollution. Polyester layer thickness is 27±2 um for 2 coatings and 32±2 um for 3 coatings. In special environment, it needs to be 4 coatings. PVDF paint is based on Kynar 500 standard and warranty is 15 years even in exterior environment.
Range of application: Aluminium composite panel, building exterior wall facade.
The Kynar500 PVDF coated coil has advantage in UV-resistance and color retention. PVDF paint warranty period is 15 years in exterior environment. Even 15 years later, it will fade little by little. With 12 years experience in colored coil field, we provide various colours for your reference.
