PVDF fluorocarbon coatings are based on PVDF resin and are applicable in aluminum work pieces and aluminum curtain walls, such as planking, extrusion profiles, shutters, window frames, beach umbrellas, windows and doors.
These coatings contain at least 70% PVDF resin in finish coat. There are two major ways (2C-lB and 3C-lB) and one minor way (roller coating) to process coatings. Proper pretreatment of substrates and special primers is essential to ensure excellent performance of the coatings. Performance test of coatings is conducted in accordance with AAMA605.2.
