LoMiCure 450 - Photoinitiator with Acrylic Function

HBEOAC (CASRN: 478549-43-8) achieves low migration (<10ppb) by incorporating itself into the polymeric film during application through an acrylic functionality

LoMiCure 450 is a photoinitiator, especially for low migration (< 10 ppb) printing inks and print varnishes. During the curing process, the photoinitiator is integrated in to the polymer film via an acrylic function, i.e. the photoinitiator itself is built into the polymeric structure during the application. By this means, potential migration can be significantly reduced in comparison to comparable polymeric photoinitiators.
