Photoinitiators

Benzophenone is a fast curing type-II photoinitiator.  In the presence of O2, the use of an amine co-initiator is recommended.  It is soluble in most monomers, oligomers and pre-polymers.  It is insoluble in H2O.

2-Isopropylthioxanthone is a Type II photoinitiator.  It is typically used in combination with tertiary amines.  Another major use is as a sensitizer to enhance the curing efficiency of both PL-907 and PL-369.  It is soluble in most monomers, oligomers and pre-polymers but insoluble in H2O.

4-Methyl benzophenone is a fast curing type-II photoinitiator.  In the presence of O2, the use of an amine co-initiator is recommended.  It is soluble in most monomers, oligomers and pre-polymers.  It is insoluble in H2O.

4-phenyl benzophenone is a very fast curing type-II photoinitiator.  In the presence of O2, the use of an amine co-initiator is recommended.  It is soluble in most monomers, oligomers and pre-polymers.  It is insoluble in H2O.

Diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide is a Type I photoinitiator best known for it's through cure abilities.  It is soluble in most monomers, oligomers and pre-polymers but insoluble in H2O.

2-Benzyl-2-dimethylamino-1-(4-morpholinphenyl) butanone is a type I photoinitiator primarily used in non-white pigmented systems.  It is oftentimes used with PL-ITX as a sensitizer to enhance the curing efficiency in inks.  It is soluble in most monomers, oligomers and pre-polymers but insoluble in H2O.

2-Methyl-1-[4-(methylthio) phenyl]-2-morpholino propan-1-one is a type I photoinitiator primarily used in pigmented systems.  It is oftentimes used with PL-ITX as a sensitizer to enhance the curing efficiency in inks.  It is soluble in most monomers, oligomers and pre-polymers but insoluble in H2O.

PL-4265 is a 50:50 liquid blend of 2-hydroxy-2-methyl-1-phenyl-1-propanone and diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide.  It provides exceptional cure response in white and pastel pigmented systems as well as thicker clear films.  It provides a perfect balance between surface cure and through cure to enable the best possible adhesion in these systems. 

PL-4265 soluble in most monomers, oligomers and pre-polymers.  It is insoluble in H2O.
