Ethyl phenyl(2,4,6-trimethylbenzoyl)phosphinate is a liquid Norrish Type I photoinitiator used to generate free radicals under UV and near-UV exposure to initiate rapid polymerization in resins, coatings, adhesives, inks, and photopolymerization-based 3D printing. It is suitable for both clear and pigmented formulations and supports two-photon induced polymerization applications.
- Liquid form for easy incorporation into resin formulations.
- Efficient radical generation under UV/near-UV light for fast cure.
- Suitable for two-photon polymerization and stereolithography processes.
- Performs well in pigmented and clear UV-curable systems for good through-cure.
- High polymerization quantum yield for effective conversion.
