Photoinitiators are the unsung heroes of UV curing technology, transforming liquid resins into solid, durable materials with the application of ultraviolet light. Among these vital compounds, Photoinitiator 369 (CAS 119313-12-1), also known as 2-Benzyl-2-(dimethylamino)-4'-morpholinobutyrophenone, stands out for its effectiveness and broad applicability. As a leading supplier of chemical auxiliaries, we aim to provide a comprehensive understanding of this crucial ingredient.

Photoinitiator 369 is classified as a Type I free radical photoinitiator. Its chemical structure allows it to efficiently absorb UV radiation and undergo unimolecular fragmentation, generating highly reactive free radicals. This process is the cornerstone of photopolymerization in UV-curable systems. Key properties that make it highly desirable for industrial use include its excellent solubility in common monomers and oligomers, its low volatility, and its characteristic yellow powder appearance. The melting point typically ranges from 110 to 119°C, and its purity is usually maintained at ≥99%.

The industrial applications of Photoinitiator 369 are extensive. In the printing industry, it is widely used in UV curable inks for offset printing, flexography, and screen printing, providing rapid curing and excellent color fidelity, especially in pigmented formulations. The coatings industry benefits from its ability to enhance the cure speed and durability of UV varnishes and finishes. Furthermore, in the electronics sector, it is integral to the production of photoresists for PCBs and solder masks, ensuring precision and reliability in electronic component manufacturing. Its low odor and migration characteristics are also advantageous for consumer-facing products.
