Fotoiniciador de alta pureza 184 CAS 947-19-3 para recubrimientos

Photoinitiator 184 (Chemical name: 1-Hydroxycyclohexyl phenyl ketone, CAS: 947-19-3) is a highly efficient Type I free-radical photoinitiator.
As a classic solid photoinitiator, 184 generates free radicals through intramolecular α-cleavage upon UV irradiation, efficiently initiating the polymerization and crosslinking of unsaturated resins and monomers. Its most outstanding performance advantage lies in its excellent yellowing resistance—even after prolonged exposure to sunlight, the cured coating exhibits minimal yellowing, making it particularly suitable for transparent clearcoats and white systems with stringent color requirements. In addition, it offers advantages such as high initiation efficiency, good storage stability, low odor, and low irritation.
