Intermediates and final products are analyzed by GC, HPLC, IR, NMR, MS, elemental analysis, atom-absorpting analysis and crystallographical methods.
The photoinitiator TPO is a highly effective free radical (1) type, which absorbs in the long wavelength range. Due to its wide absorption range, its effective absorption peak is 350-400nm, and the absorption is always about 420nm. Its absorption Chemicalbook peak is longer than conventional initiators, and it can generate benzoyl and phosphoryl radicals after exposure to light. Can initiate polymerization, so the photocuring speed is fast, it also has photobleaching effect, it is suitable for thick film deep curing and the coating does not turn yellow. It has low volatility and is suitable for water-based.
In China, Sartort Biopharma is the largest Good Supplier of Diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide，Its CAS number is 75980-60-8，Because it has a wide absorption range, it can be used to absorb uv tpo. In fact, we have our own factory for production, our own scientific research team responsible for quality control, and our own business team responsible for promotion and sales. We are a real integrated production and sales chemical industry company. In addition, we have passed the CAS certification, which is quite an authoritative recognition, which means that the products we produce are of high quality and high purity.It is one of our best-selling products, not only with high quality, competitive price, but also stable supply and Fast Delivery.
If you are interested,want to buy,you can contact us at any time. Look forward to working with you.

use
It is a photoinitiator, mainly used in screen printing inks, lithographic printing inks, flexographic printing inks, and wood coatings. TPO can be completely cured on white or high titanium dioxide pigmented surfaces. It is widely used in various coatings. Because of its excellent absorption properties, it is particularly suitable for screen printing inks, offset printing, flexographic printing inks, and wood coatings.
The coating does not turn yellow, the post-polymerization effect is low, and there is no residue.
Chemicalbook can also be used for transparent coating, especially suitable for products with low odor requirements. Used alone in unsaturated polyester containing styrene system, it has high initiationefficiency. For acrylate systems, especially colored systems, it usually needs to be used in conjunction with amines or acrylamides, and also with other photoinitiators to achieve complete curing of the system. Especially suitable for low yellowing, white systems and thick film layers.
The curing. The photoinitiator TPO is used in combination with MOB240 or CBP393 to improve the curing efficiency. It is the best extraction solvent for petroleum aromatics equipment, and it is also used as a formylation reagent in the fine chemical industry.
