Ultraviolet curing coating is an environmentally friendly and energy-saving coating developed by Bayer Company in Germany in the late 1960s. China began to enter the field of photocurable coatings in 1980s. The early producers of UV-curable resins were mainly Satomar of the United States, Japanese synthetic companies, Bayer of Germany, Changxing of Taiwan Province Province, etc. Now many domestic manufacturers are doing well, such as Miki Group and Zicai Chemical Company. In recent years, with the enhancement of people's awareness of energy conservation and environmental protection, the varieties and properties of photocurable coatings have been continuously enhanced, the application fields have been continuously expanded, and the output has increased rapidly, showing a rapid development momentum. Especially, the development of UV resin is expected to be further accelerated after coatings are included in the scope of consumption tax collection. At present, photocurable coatings are not only widely used in paper, plastic, leather, metal, glass, ceramics and other substrates, but also successfully used in optical fibers, printed circuit boards, electronic component packaging and other materials.
