英文摘要：

Waterborne UV - curable coatings is a novel type of environmental friendly coatings. It combines many advantages of the traditional UV - curable technology and the waterborne coatings technology, which has become an active research focus. This paper reviewed the characteristics, composition, functions and basic performances of waterborne UV -curable coatings. Compared to the traditional oil -based UV - curable coatings, the waterborne UV -curable coatings showed the most prominent advantage which gave a fundamental solution to the contradiction between hardness and flexibility of the traditional UV - cured coat- ings. The paper focused on the classification, the development and research progress of waterborne UV - curable resin and photoinitiator. In addition, the application and development trend of waterborne UV - curable coatings were discussed. The existing problems of waterborne UV - curable coatings and improvement were also pointed out.
