Usage
2,4,6-Trimethylbenzoyldiphenylphosphine oxide is mainly used for screen printing inks, lithographic printing inks, flexographic printing inks, and wood coatings. TPO can be completely cured on both white and high titanium dioxide pigment surfaces. Widely used in various coatings, due to its excellent absorption performance, it is particularly suitable for screen printing ink, flat printing, flexographic printing ink, and wood coatings. The coating does not yellow, the post polymerization effect is low, and there is no residue. It can also be used for transparent coatings, especially suitable for products with low odor requirements. When used alone in unsaturated polyesters containing styrene, it has high initiation efficiency. For acrylic ester systems, especially colored systems, they usually need to be used in combination with amines or acrylamides, and compounded with other photoinitiators to achieve complete curing of the system. They are particularly suitable for curing low yellowing, white systems, and thick film layers. The combination of photoinitiator TPO and MOB240 or CBP393 can improve the curing efficiency. It is the best extraction solvent for petroleum aromatic hydrocarbon plants and also used as a formylation reagent in the field of fine chemicals.
It is the best extraction solvent for petroleum aromatic hydrocarbon plants; A mixed solution of N-formylmorpholine and morpholine (1:1) is the extraction solvent for the methyl ethyl ketone unit. It is also used as a formylation reagent in the field of fine chemicals. Mainly used for screen printing ink, planographic printing ink, flexographic printing ink, wood coatings, UV curing coatings, printing ink, UV curing adhesives, optical fiber coatings, etc.
