Application
About Prepainted Aluminum Coil
Prepainted aluminum coil, which is produced with aluminum sheet or (aluminum coil) and processed by coating with color. In common sense,
there are two kinds of prepainted aluminum coil-PVDF and PE, which are widely used in aluminum plate, aluminum veneer, aluminum
honeycomb panels,aluminum ceiling, shingles, scrap, pop-top, electronics.
PVDF coatings are known for their durability and weather resistance. They provide a smooth and glossy finish, making them suitable for
architectural applications. PVDF coated aluminum coils are available in a wide range of colors and are often used for exterior cladding,
roofing, and signage.
PE coatings offer good UV resistance and color retention. They are commonly used for interior applications where extreme weather
resistance is not required. PE coated aluminum coils are available in a variety of colors and are used for indoor decorations, ceiling panels, and more.

Product Advantages
2.Uniformity of colour: The colour is uniform and consistent, with no obvious colour difference.
3.Strong coating adhesion: good adhesion between the coating and the aluminium coil substrate makes it difficult for the coating to flake, peel or lose paint.
4.Good weather resistance: PVDF coatings have a colour stability of more than 20 years compared to 10-15 years for polyester coatings. 5.Strong corrosion resistance: The natural oxidation layer of aluminium combined with a protective coating such as PVDF ensures long term durability in harsh environments.
6.Malleability: complex bending and forming without cracking.
