Use: 1069 benefits from its excellent absorption performance, making it particularly suitable for UV colored system curing, especially blue and black color system UV curing, and can even be used in systems containing ultraviolet absorbers such as. 1069 is used in the packaging field, such as offset printing, screen ink, etc., applied in the electronics industry, such as: photoresist, resistance welding ink, etc., as well as in the manufacture of printing plates. Since the initiation effect of the 1069 light initiator depends to a large extent on different formulations, the best effect and amount of addition should be obtained through formula testing.
