4,4'-Bis(diethylamino) benzophenone CAS NO.90-93-7

EMK is an effective photoinitiator for curing pigmented 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. It is used primarily in the electronics sector but also has uses in LED curing.
Suggest adding concentration is 0.1-4.0% by weight in UV-curable formulations.Type II photoinitiator,，LED Curing, suitable for colored ink curing, generally add 0.1-4.0%
