Products Description
The main absorption peak of Irgacure 369 is at 232nm and 323nm, and the absorption range can extend to the long-wave region of 350-380nm.
The Irgacure 369 has excellent absorption capacity in the long wavelength region of the ultraviolet spectrum and can effectively penetrate the pigment layer, overcoming the shielding effect of the pigment on ultraviolet light. This property makes it particularly suitable for UV-curable ink and coating systems containing pigments (especially blue and black pigments).

FAQ
Q: Could photoinitiator 369 be used for photoresist?
A: Yes. 369 has high photosensitivity. As the photosensitive component of photoresist, it is used in PCB lithography to realize pattern transfer of fine circuits.
Q: What are the storage requirements for photoinitiator 369?
A: Keep tightly sealed and protected from light in cool dry warehouse, away from UV light, heat and strong oxidants to prevent premature photodegradation and discoloration.
Q: Why is 369 suitable for high-opacity inks with black or blue pigments?
A: 369 has strong absorption of long-wave UV light. It can penetrate pigment layers to realize sufficient deep curing and improve printing quality.
Q: What benefits does photoinitiator 369 bring to PCB solder mask green oil?
A: It has high photosensitivity and delivers sharp imaging edges after exposure, ensuring high precision for fine PCB circuit patterns.
