A photoinitiator is a compound that absorbs UV or visible light and starts a polymerization reaction by generating reactive species. That is why it is essential in UV-curable inks, coatings, and adhesives.
TPO, TPO-L, 819, 907, 369, and mixed systems such as 2022 or 2100 are common starting points because they are widely used in LED-oriented formulations.
Blends are useful when a single photoinitiator does not provide the full cure balance needed by a formula.They can simplify formulation work and help match different cure-depth and surface-cure targets.
