The surface topography and structure and morphology of the coating changed a little after 25 weeks salt fog exposure. As the result, the coating resistance hold high over the period of 25 weeks.

研究结果表明，单纯盐雾老化对涂层表面形貌和结构形态没有产生明显影响，因此，盐雾老化25周后涂层仍具有较高的电化学阻抗。

Polyurea coatings with different contents of hard segment polyaspartic ester(PAE) were investigated through aging tests of marine environment outdoor exposure and salt fog testing.

通过海洋大气环境户外暴晒老化试验和盐雾加速老化试验，试验研究了不同硬段含量的聚天冬氨酸酯（PAE）聚脲涂层的耐海洋环境老化性能。
