For research scientists and product formulators, a deep understanding of chemical mechanisms is key to innovation. Photoinitiator 160, a difunctional alpha hydroxy ketone (CAS 71868-15-0), is a prime example of a chemical that enables advanced UV curing technologies. Its specific molecular structure and photochemical properties make it an invaluable component for achieving efficient and high-quality results in various UV-curable applications. Exploring its scientific underpinnings can unlock new formulation possibilities and improve existing products.

Photoinitiator 160 operates as a Type I photoinitiator, undergoing alpha cleavage upon excitation by UV light. This process generates highly reactive free radicals, which are the primary drivers of polymerization in UV-curable systems. A key scientific advantage of Photoinitiator 160 is its absorption spectrum. Compared to conventional alpha-hydroxy ketones, its molecular design is optimized to absorb radiation at longer wavelengths. This characteristic is particularly beneficial when working with pigmented systems, as pigments can absorb or scatter UV light, hindering the curing process. Photoinitiator 160's ability to absorb effectively at these longer wavelengths ensures better through-cure and surface cure, even in challenging formulations. This makes it a preferred choice for R&D teams developing advanced coatings and inks.

The development of Photoinitiator 160 represents a significant advancement in photoinitiator technology. Its difunctional nature, meaning it possesses two photoinitiating groups within a single molecule, can contribute to higher initiation efficiency. Furthermore, formulators appreciate its good coating properties, which contribute to smooth, uniform film formation. The low VOC and low migration attributes are also rooted in its molecular structure and low volatility, making it suitable for applications requiring high safety standards.
