This standard specifies the performance requirements and test methods for hot-melt fluorine Resin (PVDF) Coatings, which are mainly used for high-performance coatings of Aluminum profiles and sheets. The standard adopts the relevant regulations of the American Building Materials Association AAMA 2605-02, covering the requirements of weathering resistance, corrosion resistance and adhesion of Coatings. The Coatings are suitable for building exteriors that require long-term exposure to harsh environments to ensure the durability and aesthetics of the coatings during use.
