UV (ultraviolet, ultraviolet light) curing and EB (electronic beam, electron beam) curing are collectively referred to as radiation curing. UV curing materials are the general term for materials such as UV curing coatings, inks, and adhesives. Such materials are oligomers (also known as pre Based on polymer), it is formulated by adding specific reactive diluent monomer (also called reactive diluent), photoinitiator and various additives.

Under UV radiation, the photoinitiator in the liquid UV material is excited to become free radicals or cations, thereby initiating chemical reactions (mainly various types of polymerization reactions) between materials containing unsaturated double bonds in the material to form a cured body structure . And EB curing is by the electron beam with high energy directly interacts with the system to be cured. Due to molecular excitation and ion generation, free radicals are generated, which polymerizes, grafts or crosslinks oligomers, monomers or their mixtures, etc. The reaction eventually leads to the formation of a body structure, which solidifies the material.

UV curing has been rapidly popularized, developed and widely used due to its relatively stable reaction and far less equipment investment than EB curing. At present, UV curing occupies about 90% of the entire radiation curing market and is the researcher of new materials in the high-tech field. An important part of.

UV curing materials (UV coatings, UV inks, UV adhesives, etc.) are widely used in PCB circuit boards, microelectronics processing, papermaking, displays, household appliances, wood processing, home decoration, automobiles, printing, machinery, 3D printing, sports industries , Biomedicine, fiber optic communications and other industries.

From the perspective of the global photocuring industry's competitive landscape, due to China's strong fine chemical production capacity and cost advantages, it has developed rapidly in the production of new UV curable materials. At present, basically the main production capacity of conventional UV light-curable materials is concentrated in China, but due to the relatively small brand influence of domestic companies, they basically appear in the form of OEM in the global market. In the research and development of new varieties, foreign UV light-curable materials companies still have greater technical advantages, product innovation research and development, and application research and development capabilities.
