Research and development trend of UV curing technology

: Further study on low-hardness photocurable oligomers and low skin irritant reactive diluents

    Due to the high oligomerity of the oligomer, it is necessary to add more reactive diluent, and some reactive diluents have certain toxicity, and have certain irritation to the skin. Therefore, the research trend is to develop low-waste oligomeric varieties, macromolecular active monomers or low-skin irritant reactive diluent products, reducing the amount of reactive diluents. At the same time, the problem of difficult curing of colored systems and the problem of anaerobicity of free radical reaction systems are yet to be further studied.

二: Further research on materials used in cationic photocuring systems

    The cationic photocuring system is not interfered by oxygen inhibition, and the curing shrinkage is small, but currently there are few varieties of cationic photocurable resins and reactive diluents, which limits the development of the system. Further synthesis and search for resins and reactive diluents suitable for cationic photocuring systems, varieties of cationic photoinitiators have yet to be developed, and synthetic methods and photoinitiation efficiencies need to be improved.

三: Computer simulation and auxiliary design of radiation curing equipment

    With the wide application of UV-curable coatings, construction objects range from simple to complex, coating surfaces from flat to three-dimensional surfaces, which also puts higher demands on photocuring irradiation systems. For workpieces with complex shapes, traditional process equipment, irradiation systems, and products are difficult to achieve the required performance, so it is necessary to use a computer to simulate and design the ultraviolet curing coating irradiation system.

  In short, UV-curable coating technology has strong vitality and unlimited market development space because of its outstanding advantages such as no pollution, high efficiency, high performance, energy saving and resource saving. It is believed that as new resins, photoinitiators and new formulations continue to emerge, and radiation curing systems continue to improve and improve, their applications will become wider and wider.
