This standard puts forward the technical requirements for vacuum coating endothermic materials of solar collectors, which are in line with the market demand for endothermic materials. Its key technical indicators are: coating, coating adhesion, salt spray resistance of endothermic materials, high temperature durability, The coating's aging resistance and acid and alkali resistance are better than the national standard.
