Product introduction：
4,4′-Bis(diethylamino) benzophenone is an effective photoinitiator for curingpigmented and clear UV-curable, acrylate-based coatings, adhesives and inks. It can be used as a photosensitizer and an amine synergist. A strong absorption between 350 to 400nm makes it most suitable for pigmented and black UV coating. Suggest adding concentration is 0.1-4.0% by weight in UV-curable formulations.
