The selection of the right photoinitiator is critical for the success of any UV curing formulation. While a variety of photoinitiators are available, Photoinitiator 369 (CAS 119313-12-1) consistently stands out for its unique performance profile. This article compares its advantages, providing insights for R&D scientists and formulators deciding on the best chemical additive for their needs.

Photoinitiator 369 is a highly efficient Type I free radical photoinitiator. Its primary advantage lies in its exceptional performance in dark or heavily pigmented UV curable systems. Unlike many other photoinitiators that struggle with absorption in these challenging formulations, Photoinitiator 369 exhibits strong UV absorption across a broad spectrum, ensuring thorough and rapid curing. This makes it an ideal choice when you need to buy Photoinitiator 369 for applications in printing inks, industrial coatings, and certain specialty varnishes where color intensity is a factor.

Another key differentiator is its low mobility and low odor characteristics. These features are increasingly important for end-product safety and environmental considerations. The reduced migration potential minimizes the risk of the photoinitiator leaching from the cured film, while its low odor contributes to a better working environment and a more pleasant user experience. For manufacturers, this translates to higher quality products that meet stricter regulatory standards.

When considering alternatives, other photoinitiators might offer faster cure speeds in clear systems or different absorption wavelengths. However, for applications demanding performance in pigmented systems or requiring low odor and migration, Photoinitiator 369 often proves superior. As a leading manufacturer and supplier in China, we offer this high-quality photoinitiator with competitive pricing, making it an attractive option for formulators seeking optimal performance and value.

We encourage formulators to consider Photoinitiator 369 for its balanced profile of efficiency, specialized performance, and safety features. Its ability to tackle challenging UV curing scenarios makes it a valuable addition to any formulator's toolkit.
