PVDF Coating Aluminum Profiles are engineered to offer unparalleled performance and durability for a wide range of architectural applications. Through PVDF fluorocarbon spraying treatment, the aluminum profile has super weather resistance and self-cleaning properties, with long-lasting color, and is suitable for high-rise building curtain walls, billboards, etc.
The self-cleaning properties of PVDF coatings provide an added layer of convenience, significantly reducing the need for maintenance. Water and dirt are effortlessly repelled, keeping the profiles pristine even in high-rise buildings and hard-to-reach areas. The superior coating also guarantees long-lasting color retention, preventing fading or discoloration over time, which ensures the profiles retain their visual appeal throughout their lifecycle.
