Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide CAS 75980-60-8

Application：

As a photoinitiator, it is mainly used for screen printing ink, offset printing ink, flexographic printing ink, and wood coatings. TPO can completely cure on white or high titanium dioxide pigment coated surfaces. Widely used in various coatings, due to its excellent absorption performance, it is particularly suitable for screen printing ink, offset printing, flexographic printing ink, and wood coatings. The coating does not turn yellow, with low post polymerization effect and no residue. It can also be used for transparent coatings, especially suitable for products with low odor requirements. Chemicalbook, when used alone in unsaturated polyesters containing styrene, has a high initiating effect. For acrylic ester systems, especially colored systems, it is usually necessary to use them in combination with amines or acrylamide, as well as other photoinitiators, to achieve complete curing of the system. This is particularly suitable for curing low yellowing, white systems, and thick film layers. The use of photoinitiator TPO in combination with MOB240 or CBP393 can improve the curing efficiency. It is the best extraction solvent for petroleum aromatics units and also used as a formylation reagent in the field of fine chemicals.
