Some of these systems use maleic anhydride (MA) derivations or maleimides (made from maleic anhydrides), tertiary amines, and an UV absorbent cosynergist (3).
Abstract Isopropylthioxanthone is a popular cosynergist for Type II and three-component photoinitiators used to photopolymerize ultraviolet (UV) curable coatings and can be used in the presence of maleic anhydride derivatives to efficiently cure coatings used in numerous applications.
