Irgacure 819, is an acylphosphine oxide photoinitiator, chemically named Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide.
Irgacure 819 is a key component of light-curing materials, and it plays a decisive role in the light-curing speed of light-curing materials.
Irgacure 819 is a substance that can absorb radiant energy, undergo a photochemical change upon excitation, and produce reactive intermediates (free radicals or cations) that have the ability to initiate polymerization.
The current photocuring technology is mainly UV curing, and the photoinitiator used is the UV photoinitiator.

|Conclusion ||Conform |
1.UV-curable coatings and inks
2.Photoinitiator 819 is a highly efficient, general-purpose UV photoinitiator for initiating UV polymerization of unsaturated prepolymerization systems.
3.Printing inks and prepreg systems for wood, metal, plastic, paper and fiber surfaces
4.Irgacure 819 In white paints, colored paints and inks containing titanium dioxide or other pigments with high hiding power, adding a small amount of Phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide can make the coating have excellent curing effects and resistance. UV yellowing performance.
5.Because 819 has excellent absorption properties, it can be used in thick film systems.
6.Irgacure 819 can be used in conjunction with other photoinitiators, such as 184 or 651.
7.The combined use of Irgacure 819 and 651 is particularly suitable for curing polyester/styrene resin systems, such as glass fiber reinforced materials.
8.Because it also absorbs in the long wave band, Irgacure 819 can be used in conjunction with a UV absorber, such as TINUVIN 400, so it can be used in UV curable coatings that require weather resistance.
