The first patent for ultraviolet (UV) curing coating was born in 1947. After more than half a century of development, UV curing coating has become a relatively mature technology, especially with the improvement of people's environmental awareness. , production and researchers pay more attention to the development and application of UV curing coatings. UV curing coating is a green and environmentally friendly coating. It fully complies with the "4E" principle. Generally, UV curing energy consumption is 1/5 of thermal curing. UV curing coatings contain less volatile components and cause less pollution, which is the most attractive to researchers. What developers like is that UV curable coatings can reduce raw material consumption and help reduce economic costs.
