IGM supplies cationic photoinitiators for cationic printing inks and overprint varnishes aimed at niche applications such as can coating, coil coating and pharmaceutical packaging. Cationic photoinitiators are ideally suited for these coatings due to their low viscosity, high solvent resistance, low shrinkage after polymerization, and superior adhesion. Some are free of benzene and characterized by low odor. The Omnicat range is available as a powder as well as a dilution.
Mixture of triarylsulfonium hexafluorophosphate salts and propylene carbonate, for
