Traditional coil coatings mainly adopt thermal curing process, however, the process is characterized by high energy consumption, slow curing speed and high organic matter emission,it is difficult to meet the requirements of high efficiency coating process and environmental protection. UV-curing is an environmental friendly processing technology. Compared with traditional thermal curing, UV-curing has many advantages such as low energy consumption, low pollution, fast curing speed and good performance of products, which especially is suitable for high-speed coating of automatic production lines. In this paper, the technical characteristics and technological requirements of coil coatings, the development and research progress of UV-curing technology in coil coatings are described. The characteristics and main components of UV-curing coatings are discussed. The current problems and future development of UV curing are pointed out.
