Product Information of Photoinitiator 2959

Photoinitiator 2959 is the only FDA-certified system that allows for the use of photoinitiators, low odor, low volatility, low yellowing, and reactive hydroxyethoxy end hydroxyl groups that can participate in the reaction. It can be used in aqueous photocuring systems. It can be used in adhesives that are not in direct contact with foods. It has a high melting point and can also be used in UV curable powder coatings. It is mainly used as UV coating, ink and adhesive sensitizer in the initiation process. It is better than (ITX+EDAB) and BDK, is not sensitive to oxygen inhibition, and has low volatility and excellent surface curing effect. The spectral absorption band is mainly in the short wavelength band, and the deep curing effect for the UV pigment system is not very good, and it is best to use it together with 369.
