The PVDF coating for aluminum coil refers to a vinylidene fluoride homopolymer or a copolymer coating including vinylidene fluoride and a small amount of a fluorine-containing vinyl monomer. Its stability and solidity in chemical structure makes its physical properties different from the general coating.
In addition to the excellent mechanical properties like wear resistance and impact resistance, the PVDF coated aluminum coil also shows lasting fade resistance and UV resistance especially in the harsh climate and environment.
After being baked into film under high temperature, the coating achieves tight molecular structure, thus providing the aluminum coil with superior weather resistance. Therefore, this selection of color coated aluminum coil is especially suitable for indoor and outdoor decoration in public places, as well as decoration and display in commercial chains, exhibition advertising, etc. It is your best choice if you are looking for painted aluminum sheets, aluminum building material, aluminum decoration material, etc.
