Main Applications of Photoinitiator EMK

  1. Photoinitiator EMK is used as a dye intermediate for the synthesis of triarylmethane dyes, such as basic brilliant blue BO; it can also be used as a photosensitizer in the film film industry; as a special optical material for the microelectronics industry; Rubber crosslinker. It is obtained by reacting N,N-diethylaniline with phosgene, and can also be synthesized by an oxidation method.
  2. It mainly used for high-efficiency UV curable colored coatings & inks.
  3. Used as a dye intermediate.

Storage Conditions: Store in a cool and dry place, and prevent from sunlight.
