Photoinitiators & Synergists

Photoinitiators enable extremely fast cure speeds, excellent depth of cure in properly formulated systems, and compatibility with various monomer chemistries. Photoinitiators prove essential in radiation-curable adhesives, making them valuable for electronics assembly, medical devices, and high-speed manufacturing. 

Sub-types include free-radical photoinitiators like benzophenones and phosphine oxides triggering acrylate polymerization, and cationic varieties enabling cure of epoxy systems. Specialized grades offer enhanced surface cure, reduced oxygen inhibition, or activation by specific wavelengths for selective curing. Recent innovations focus on polymeric photoinitiators.
