Anwendungen & Verwendung

Beschreibung

2-Isopropylthioxanthone (ITX) has been widely used in many processes, such as printing inks, surface coatings, microelectronics, and photoresists. Nevertheless, it was also widely used in UV curing to promote the polymerization of inks used in paper- or plastic-based packaging materials because of its high photoinitiation efficiency and absorption characteristics at near-UV range (370385 nm).

Verwenden

2-Isopropylthioxanthone is a thioxanthone derivative useful as photoinitiators.
