Photoinitiator 369
2-Benzyl-2-(dimethylamino)-1-(4-morpholinophenyl)-1-butanone
Low-odor amino ketone with excellent UV LED response for inks and adhesives.
Product Description
Photoinitiator 369 is a second-generation α-amino ketone combining an anilino-morpholine chromophore with a benzyl-dimethylamino cleavage center. It absorbs efficiently in the near-UV/visible boundary region, giving it a strong response on 385–405 nm UV LED arrays while remaining fully active under mercury lamps.
Compared to 907, 369 offers lower odor and improved compatibility with low-migration food-packaging inks. Typical use levels are 1–4 wt% alone or 0.5–2 wt% with acylphosphine oxides for balanced LED curing.
Key Features
- Strong 385–405 nm UV LED response
