(2) Product Detail

Photoinitiator TPO

Chemical Name: 246-trimethylbenzoyldiphenyl phosphine oxide

CAS No. : [75980-60-8] 

Formula: C₂₂H₂₁O₂P

Formula Weight: 348.37

Chemical Structure:  

Appearance: light yellow powder

Purity:  99.0%min    

Melting Point: 90.0-94.0 ℃  

Loss Rate：Volatile Matter：≤0.5%;  Ash Content：≤0.1%；

Dlarity：10 g /  100 ml toluene

Advantages:  

1. Its photocuringspeed is fast

2. Have light-decolourizatio

3. Can be used for thick coating curing 

4. Belongs to low-volatilitymild-smell and environment friendlyproduct

5. Anti-yellowing 

Character and Application:

TPO appears light yellow powdermelting point is at 90-94℃and 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 rangeis wider than conventional photoinitiatorsand it can absorb well different wavelength UV-lights. It can generate two free radicals——benzoyl and phosphorus acyl which both can initiatepolymerizationthereforeits photocuringspeed is fastand that it has light-decolourizatiois suitable for thick film deep curingmoreoverthe coating doesn’t turn to yellowand it is also fit for water basewith the characteristicof low volatilitymild smell and anti-yellowing.
