PVDF (Polyvinylidene fluoride) Prepainted Galvanized Steel Coil is a type of pre-painted steel coil that has been coated with PVDF resin and then baked at a high temperature to produce a durable and weather-resistant finish. PVDF is a high-performance coating that offers excellent resistance to weathering, fading, and chalking, making it ideal for use in harsh outdoor environments.
PVDF Prepainted Galvanized Steel Coil is made by cleaning and treating the galvanized steel surface with a series of chemical processes to ensure good adhesion of the PVDF coating. The steel coil is then coated with a primer layer, followed by a topcoat of PVDF resin, which is applied using a roll coating process. The coated steel coil is then baked at a high temperature to cure the PVDF coating and ensure that it bonds firmly to the steel surface.
