Photoinitiator ITX

Photoinitiator ITX (Isopropylthioxanthone) is a highly efficient Type II photoinitiator widely utilized in ultraviolet (UV) curing applications, prized for its strong absorption in the medium to long-wave UV spectrum. Its primary function is to absorb UV light energy and, in the presence of a co-initiator (typically an amine), generate free radicals that initiate the polymerization of monomers and oligomers. This mechanism makes ITX a cornerstone technology for producing high-performance, solvent-free coatings and inks with rapid cure speeds and enhanced physical properties.
The appearance of Photoinitiator ITX is a slightly yellow crystalline powder, stable at room temperature, and needs to be stored in a dark sealed container. This substance belongs to the class of thioanthrone photoinitiators, with a maximum absorption wavelength of 382nm, matched with mercury lamp light source. It is mainly used in the fields of UV curable coatings, inks, and photoresists, which can reduce yellowing of the curing system and extend storage life.
