PVDF coated aluminum coil

PVDF coating is a fluoropolymer resin-based coating system containing PVDF resin, pigments, solvents and additives. PVDF coating has excellent weather resistance, UV resistance, corrosion resistance and durability. It retains its bright and shiny appearance even after 20 years of outdoor exposure.

PVDF coatings can be divided into traditional PVDF and nano-PVDF coatings, depending on the size of the pigment particles. Traditional PVDF coatings have smooth and glossy surfaces, while nano PVDF coatings have matte and textured surfaces.

PVDF coated aluminum coils are suitable for applications requiring high performance and aesthetics, such as curtain walls, roofs, cladding, etc. It can also be used for special purposes, such as anti-scratch, antibacterial, food grade packaging.

PE coated aluminum coil

PE coating is a coating system based on polyester resin, containing polyester resin, pigments, solvents and additives. PE coating has good gloss, rich color and mechanical properties. It protects aluminum coils from UV radiation, wind, rain, frost and snow.

PE coatings can be divided into high-gloss PE and matte PE coatings according to the glossiness of the surface. PE coated aluminum coil is suitable for applications that require medium performance and cost-effectiveness, such as interior decoration, billboards, signboards, etc.
