What is 4-Benzoylbiphenyl CAS 2128-93-0?

4-Benzoylbiphenyl is a highly efficient free radical (II) type solid photoinitiator, mainly used with tertiary amine synergist for unsaturated prepolymer (such as: acrylate) UV curing. 4-Benzoylbiphenyl belongs to the long-wave absorbing molecular structure of the initiator, mainly used in colored UV curing formulations as a light-curing initiator. 4-Benzoylbiphenyl unique odorless characteristics, can be used in direct contact with food, widely used in a variety of food packaging UV ink, varnish and other systems have strong absorption properties. The recommended dosage is 2-5%w/w.
