The field of UV curing has revolutionized many industries, from printing and packaging to coatings and electronics, thanks to the development of efficient photoinitiators. These compounds are the catalysts that enable rapid polymerization and hardening of inks, coatings, and adhesives upon exposure to ultraviolet light. Among the diverse range of UV photoinitiators available, Photoinitiator EMK (CAS 90-93-7) has emerged as a significant player due to its effectiveness and versatility.

Photoinitiator EMK, chemically known as 4,4′-Bis(diethylamino) benzophenone, is characterized by its light yellow powder appearance and high purity, typically ≥99.0%. Its primary function is to absorb UV radiation and initiate the free-radical polymerization process. This makes it invaluable in applications such as UV curable coatings and inks, where fast curing speeds, excellent adhesion, and durable finishes are required. The compound's specific absorption spectrum, which peaks within the 245-375 nm range, is well-suited for many standard UV curing lamps, ensuring efficient energy transfer and rapid polymerization.

Furthermore, Photoinitiator EMK is known to exhibit a synergistic effect when used in conjunction with active amine co-initiators. This combination can significantly enhance the curing rate and improve the surface cure, making it an excellent choice for demanding applications. Its ability to perform well in pigmented systems, where UV light penetration can be challenging, also adds to its appeal for formulators.
