Photoinitiator is the most important part of the composition of light-curing adhesives. Because UV glue must be cured under the irradiation of ultraviolet light, once the photoinitiator is lacking, the irradiation energy cannot be used, and the light irradiation intensity cannot be used. Therefore, the photoinitiator is particularly important for the shadowless glue.
When choosing the photoinitiator for the photoinitiator in the uv glue, it should be noted that its absorption spectrum should match the emission spectrum of the light source. At the same time, for better response, a composite photoinitiator can be used. Only by using a good photoinitiator, UV glue curing can achieve the best results.
