Irgacure® 250is a versatile photoinitiator for cationic polymerization of epoxy- or oxetane-based photo-curable systems upon light exposure. It can be used to effectively cure cationic inks and coatings, e.g., printing inks, white base coatings and adhesives. Irgacure® 250 is especially suitable to the cure thick and highly pigmented systems.
Irgacure® 250 may be used alone or in combination with suitable photosensitizers, such as thioxanthones, in UV-curable inks and varnishes for application on paper, metal, wood, plastic materials and adhesives. When used in combination with α-hydoxyketones, excellent surface curing can be obtained at sub¬stantially higher line speeds. Imaging applications in graphic arts (e.g., flexo and screen inks, white base coatings) may be of specific interest. Irgacure® 250 is also well suitable for adhesives applications.
