162881-26-7

Product Name: Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide

Other Name: Photoinitiator 819; Irgacure 819

CAS No.: 162881-26-7

Formula: C26H27O3P

Structure:

162881-26-7

Assay: 99%

Application:

CAS 162881-26-7(Photoinitiator 819) may be used, after adequate testing, in UV curable formulations for clear and for pigmented coatings on wood, metal, plastic, paper and optical fibers as well as for printing inks and prepregs.

 

CAS 162881-26-7(Photoinitiator 819) exhibits at low concentrations an outstanding curing performance in highly opaque white and colored furniture coatings or screen inks containing rutile titanium dioxide or colored pigments and affords minimum yellowing after exposure to sufficient amounts of UV radiation. Additionally the outstanding absorption properties of CAS 162881-26-7(Photoinitiator 819) allow curing of thick sections.

 

With the latter it is especially suited to cure polyester/styrene resins as used for glass reinforced materials. Due to its photosensitivity at longer wavelengths, CAS 162881-26-7(Photoinitiator 819) can easily be used in combinations with UV absorbers, e.g. TINUVIN 400. It is therefore ideally suited for use in weather-resistant UV curable coatings.
