TCI America 4,4'-Bis(diethylamino)benzophenone B0139

4,4'-Bis(diethylamin o)benzophenone / N,N,N',N'-Tetraethyl -4,4'-diaminobenzoph enone Photopolymerization initiators are used in many fields to generate photocurable composites. These composites are polymerized by irradiation with UV light and electron beam which leads to altered physical properties of the composites such as solubility, viscosity and adhesiveness. In particular, the phenomenon in which a liquid changes into a solid is most useful and is applied to surface-treating techniques in fields including paints, printing inks, dental materials, lithography, photoresist, etc. A growing number of intensive studies have been made for the development of improved properties for novel photopolymerization initiators.
