Plastics manufacturing

Photocurable

  • Light absorption in long-wavelength region, and has excellent solubility.
  • Shows high stability in different monomers.
  • Generates diethylamine (b.p. =55°C) of secondary amine by light irradiation.
  • Can be used as a sensitizer for WPBG-300 and WPBG-345.
