2,4,6-trimethylbenzoyldiphenyl phosphine oxide
light yellow powder
Loss Rate:Volatile Matter
10 g / 100 ml toluene
TPO appears light yellow powdermelting point is at 90-94'Cand it has enough solubility in active diluents.
Since it has a wide range of absorptionthe typical absorptions are at 365nm380nm400 nmand the maximum
absorption wavelength is about 425nmits absorption range is wider than conventional photoinitiatorsand
it can absorb well different wavelength UV-lights. It can generate two free radicals——benzoyl and phosphorus
acyl which both caninitiatepolymerizationthereforeits photocuring speed is fastand that it has
light-decolourizatiois suitable for thick film deep curingmoreoverthe coating doesn’t turn to yellowand it is also
fit forwater base with the characteristic of low volatilitymild smell and anti-yellowing.
This product usually be used in the white systemcan be used in UV cure coatingsprinting inkUV curing

The usage of this product should base on the results of practicalexperimentsand the suggested volume of addition is 0.5-5 % (w/w).
In consideration of that TPO also absorbs a little in the visible regionit should be protected from light in the process of storage and transportation.
1. Its photocuring speed is fast
2. Have light-decolourizatio
3. Can be used for thick coating curing
4. Belongs to low-volatilitymild-smell and environment friendly product
