For R&D scientists and formulators in the field of photochemistry and polymer science, the selection of the right photoinitiator is critical for achieving desired material properties and performance characteristics. Photoinitiator 94576-68-8 (CAS: 94576-68-8), chemically known as 1-(biphenyl-4-yl)-2-methyl-2-morpholinopropan-1-one, has emerged as a powerful tool in the development of advanced UV-curable systems. As a leading chemical supplier, we provide detailed insights into this versatile photoinitiator.

Photoinitiator 94576-68-8 is a new generation photoinitiator that offers significant advantages over older, traditional compounds. Its chemical structure and properties make it a preferred choice for applications demanding high performance, safety, and environmental compliance. If you are researching new formulations or optimizing existing ones, understanding its profile is essential.

Chemical Properties and Mechanism

Photoinitiator 94576-68-8 is characterized by its molecular formula C20H23NO2 and a molecular weight of approximately 309.4. It typically presents as an off-white to yellow powder with a melting point between 120-125 °C. The key to its functionality lies in its ability to efficiently absorb UV light and undergo a cleavage or hydrogen abstraction process (depending on the specific formulation and wavelength) to generate free radicals. These free radicals then initiate the rapid polymerization of monomers and oligomers, such as acrylates and methacrylates, leading to the formation of a solid, cross-linked polymer network.

Its advantages include:

  • Benzene-Free Structure: Unlike some older photoinitiators, this compound does not contain benzene in its molecular structure, which is a significant benefit for safety and regulatory compliance.
  • Excellent Anti-Yellowing: R&D scientists often face the challenge of yellowing in UV-cured materials. Photoinitiator 94576-68-8 provides superior resistance to yellowing, making it ideal for clear coats, white formulations, and applications where color stability is paramount.
  • Low Odor and Low VOC: The absence of residual odor after curing and its contribution to low VOC emissions make it suitable for environmentally sensitive applications and improve the overall user experience.

Applications in Research and Development

The unique combination of properties makes Photoinitiator 94576-68-8 highly versatile for R&D purposes:

  • UV-Curable Inks and Coatings: Essential for developing inks and coatings with fast cure speeds, excellent adhesion, and high scratch resistance, especially for packaging and graphic arts.
  • Adhesives and Sealants: Facilitates the rapid bonding of various substrates in industrial assembly processes, where precise and quick curing is needed.
  • 3D Printing and Additive Manufacturing: Its efficiency is valuable in photopolymer resin formulations for 3D printing, enabling rapid layer curing and the creation of complex geometries with high resolution.
  • Electronics: Used in photoresists and encapsulants for electronic components where precise curing and material integrity are critical.
