We emphasize the quality and reliability that NINGBO INNO PHARMCHEM CO.,LTD. brings to the supply of this crucial material.

Chemical Profile and Mechanism of Action

UV Photoinitiator DETX (CAS No. 82799-44-8) is characterized by its chemical name, 2,4-diethylthioxanthen-9-one. With a molecular formula of C17H16OS and a molecular weight of 268.37, it possesses a distinct yellow crystalline powder appearance. Its melting point typically ranges from 66-70°C, and its density is around 1.178 g/cm³. These physical properties are vital for formulators when designing UV-curable systems.

As a Type II photoinitiator, DETX operates by a process of hydrogen abstraction. When exposed to UV radiation, it undergoes excitation and then interacts with a hydrogen donor, usually a tertiary amine. This interaction generates free radicals, which are the initiators of the polymerization process. This mechanism is highly effective for curing unsaturated monomers and oligomers, such as acrylates, commonly found in UV-curable inks, coatings, and adhesives. The recommended addition level is typically between 0.25-3%, depending on the specific formulation and curing conditions, making it a very efficient highly efficient UV photoinitiator.

Diverse Applications of DETX

The adaptability of UV Photoinitiator DETX makes it suitable for a wide range of applications, cementing its status as a versatile component in UV curing technology.

  • UV Curable Inks: DETX is widely used as a UV curable inks catalyst, ensuring rapid and complete curing of inks used in printing applications. This is critical for achieving sharp images, vibrant colors, and durable prints on various substrates.
  • Pigmented Paints and Coatings: For systems that contain pigments, which can absorb or scatter UV light, DETX proves particularly effective. It facilitates efficient curing in applications like metal decorative paints and anti-welding paints, ensuring a tough and aesthetically pleasing finish. Its role as a metal decorative paint photoinitiator is well-established.
  • Adhesives: As a crucial UV photoinitiator for adhesives, DETX enables fast bonding in manufacturing processes. Its rapid radical generation ensures quick tack and full cure, enhancing assembly line efficiency.
  • Other UV Curable Systems: DETX can also be used in photocuring applications when paired with anionic initiators, further broadening its utility in specialized formulations for coatings and other materials.
