2-Hydroxy-2-Methyl-1-Phenyl-Propane-1-One (Photoinitiator 1173)
2-Hydroxy-2-Methyl-1-Phenyl-Propane-1-One (Photoinitiator 1173) is an efficient free-radical photoinitiator. It has good solubility in most monomers/resins, fast UV curing response and low post-curing yellowing. Widely used in UV-curable coatings, inks, adhesives and 3D printing resins, it effectively initiates acrylate and unsaturated polyester polymerization for rapid and full curing.
