Photoinitiator 1173

YS-1173 is a general free radical photoinitiator and one of the most mature photoinitiators.

Photoinitiator 1173 is widely used in UV curing materials due to its excellent cost performance and relatively balanced properties, especially for wood coating and basic coating.

Photoinitiator 1173 is a highly efficient and non-yellowing UV photoinitiator. In the UV curing systems of unsaturated polyester and multi-functional monomers, it has low odor, non-yellowing, and good color stability features. It can be easily compounded with other photoinitiators.

Photoinitiator 1173 is suitable for acrylic UV-curable clear coating systems, such as those for wood, metal, paper, and plastics. It can also be applied in the fields of UV plastic coatings, UV wood coatings, and UV paper inks. It is suitable for colorless systems and can be paired with photoinitiator 907, especially photoinitiator TPO and photoinitiator 819 for use in colored paints.
