Chemical name: 2-Benzyl-2-(dimethylamino)-4'-morpholinobutyrophenone CAS No.: 119313-12-1 Molecular formula: C23H30N2O2 Molecular weight: 366.5 Appearance: Slightly yellow powder Purity, %: 99min. Melting range, degree: 110 - 119 Volatility, %: 0.3max. Photoinitiator 369 is a highly efficient photoinitiator which combines fast cure response in dark colors, low migration and reduced odor on UV exposure. It is used for the photopolymerization of free radicals. It is used in UV curing inks and coatings. It is very suitable for the curing of UV colored system, especially the blue and black color phase system UV curing, and even the systems containing ultraviolet absorbents. It is also applied to the offset printing, silk screen printing ink, printing plates etc. It can be used in combination with other photoinitiators such as 184, 651, 907, ITX.

184 has a high light triggered activity, good thermal stability and does not produce the yellowing is the most commonly used Photoinitiator maximum absorption wavelength of 333nm, mainly used to trigger the system of acrylate and methyl acrylate fast curing.

Chemical name: 2-Dimethylamino-2-(4-methyl-benzyl)-1-(4-morpholin-4-yl-phenyl)-butan-1-one CAS No.: 119344-86-4 Molecular formula: C24H32N2O2 Molecular weight: 380.5 Appearance: Pale yellow crystal Purity, %: 98.5min. Melting point, degree: 87 - 93 Loss on drying, %: 0.25max. Ash, %: 0.1max. Photoinitiator 379 has good curing effect in tint/dark pigments, good solubility in acrylate solution and has good dispersibility. Applicable to mixed liquids: good versatility in formulations of various color systems, high efficiency in application of dark thick film coatings; can be used as ink additives in high efficiency/high performance printing process; excellent film performance. Its red-shifted adsorption spectrum makes it especially suitable for UV curable inks. It can be used alone or in combination with suitable co-initiators, such as 184, 651 or ITX etc.
