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.
Photoinitiator PBZ is an efficient free radical photoinitiator used for UV polymerization of corresponding resins with co initiator tertiary amine. It is suitable for paints, adhesives, plastic coatings, wood coatings, and printing inks
