Is the UV curable adhesive component-photoinitiator really important?

Mar 27,2025

Photoinitiator is an 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 reached. , So the photoinitiator is particularly important for the shadowless glue.

The photoinitiator in the uv glue should pay attention to its absorption spectrum to match the emission spectrum of the light source. At the same time, for better reaction, a composite photoinitiator can be used. Only by using a good photoinitiator, the curing of UV glue can achieve good results.
