Aluminium Coil for Roofings PVDF (polyvinylidene fluoride) coated aluminum coil is a type of coated aluminum that has a PVDF resin coating applied to its surface. This coating provides the aluminum with excellent resistance to weathering, UV radiation, and corrosion. It is also resistant to stains and is easy to clean, making it suitable for use in a variety of applications. PVDF coated aluminum coil is commonly used in the construction industry, particularly for cladding buildings and other structures. It is also used in the manufacture of roofing, siding, and flashing, as well as for window and door frames. PVDF coated aluminum coil is also used in the transportation industry, for applications such as aircraft and automotive parts. It is also used in the production of signage and other types of visual displays. PVDF Application Process There are several steps involved in the PVDF (polyvinylidene fluoride) coating process: Surface preparation: The surface of the aluminum must be properly cleaned and treated to ensure that the PVDF coating adheres properly. This may involve degreasing, sandblasting, and/or etching the surface. Priming: A primer coat is applied to the aluminum surface to help improve the adhesion of the PVDF coating. Applying the PVDF coating: The PVDF coating is applied to the aluminum surface using a variety of methods, such as spraying, roller coating, or curtain coating. Drying: The coated aluminum is then placed in a drying oven to allow the PVDF coating to cure and harden. Quality inspection: The coated aluminum is inspected to ensure that it meets the required standards for thickness, appearance, and performance. Packaging and storage: The coated aluminum is then packaged and stored until it is ready to be shipped to the customer. It is important to follow proper handling and storage procedures during and after the PVDF coating process to ensure that the coated aluminum maintains its optimal performance and longevity.
