PHOTOINITIATOR 250 by Cheermove is a versatile photoinitiator for cationic polymerization of epoxy- or oxetane-based photo-curable systems upon light exposure. It can be used alone or in combination with suitable photosensitizers such as thioxanthones. It is especially suitable to cure thick and highly pigmented systems. It is recommended for UV-curable inks and varnishes for application on paper, metal, wood and plastic materials. When used in combination with a-hydoxyketones, excellent surface curing can be obtained at substantially higher line speeds. PHOTOINITIATOR 250 is also used in graphic arts (e.g., flexo and screen inks, white base coatings). Recommended dosage level is 0.3-3%. It has a shelf life of 1 year.
