English name: 2-Benzyl-2- (dimethylamino) -1- [4- (4-morpholinyl) phenyl] -1-butanone Molecular formula: C23H30N2O2 Molecular structural formula: 369 Molecular weight: 366.5 CAS NO： 119313-12-1 Appearance: Light yellow powder Content:>99.0% Melting point: 110-119 ℃ Absorption wavelengths: 232, 323nm A photoinitiator with a high photosensitive range and good UV absorption, characterized by low mobility and low odor, particularly suitable for rapid curing of dark colored systems. It can be used alone or in combination with appropriate co initiators such as UV184 or UV651 for UV curable inks and paper, metal, and plastic paints UV369 benefits from its excellent absorption performance, making it suitable for UV curing inks and colored systems, and even for use in systems containing UV absorbers such as SUNSORB1130. UV369 is applied in the fields of photography, art (such as offset printing, screen printing ink, etc.), electronics industry (such as photoresist, solder mask ink, etc.), and manufacturing of printed boards. Suggested addition amount: Offset ink 2-4% Screen ink 2-4%+1-3% UV184 Color paint 1-4% Phase forming photosensitive resin 0.5-5%
