海洋环境中，钢结构的腐蚀不可避免，有机涂层是一种延缓金属腐蚀的最有效、最经济的材料之一。其中高固体分环氧涂料由于绿色环保、涂层致密性好、可厚涂等特点在海洋重防腐中得到广泛的应用。对目前高固体分环氧厚膜、超厚膜涂料的研究进展，存在的问题及解决方法进行了详细的介绍。其中，环氧树脂、胺类固化剂作为环氧涂料中的主要的成膜物质，对涂层的性能起着关键的作用。总结了几种在高固体分环氧涂料中切实可行的环氧树脂增韧改性方法，同时指出开发耐冲击性能优异，耐高温，低温固化、水下固化的环氧固化剂也是环氧固化剂的发展趋势。通过曼尼希碱改性合成的环氧固化剂，恰好能满足各种性能的要求，阐述了该类环氧固化剂的合成研究进展状况。
