  • Improving curing rate

UVS-1331 sensitizes and activate photo-initiators that do NOT show a sufficient performance under long wave UV-LED such as 365nm, 385nm, 395nm and 405nm.
In addition, UVS-1331 accelerates curing rate compared with onium salts alone. UVS-1101 shows a similar result as well.
