5. Main Application
PVDF resin mixed with acrylic resin and additives can form baking PVDF fluorocarbon coating with superior performance. The coating can be used for aluminum workpieces and aluminum curtain walls, such as plates, profiles, window frames and door frames, with a service life of more than 20 years. The base material must be pretreated before coating. Generally, the construction process of two coating and one drying and three coating and one drying is adopted. It is applicable to the surface of aluminum substrate such as building curtain wall, doors and windows, ceiling, roof and shop facade.
