Abstract To observe the aging performance of AF magnetism coatings with different substrates, the exposure test in Xisha marine atmospheric environment carried out, and series of performance evaluation such as gloss, color, the degree of chalking and SEM were applied to test the transformation of surface topography and properties, and the contrast was completed. The results were: the anti -weathering of AF magnetism coating was wrong in outdoor atmospheric environment, and the anti-weathering of AF magnetism coating was preferable in indoor atmospheric environment; In indoor atmospheric environment the anti-weathering of AF magnetism coating with LY12-CZ substrate and Q195 substrate was better than the anti-weathering of AF magnetism coating with LF6M substrate; The primary causes of coating aging are the illumination, temperature and humidity, and the strong illumination, high temperature and high humidity of Xisha accelerate the aging of coating.
