High refractive index material

Feature

  • Monomer for high refractive index resin composition (nD:approximately 1.69)
  • This monomer is Low-viscosity (≦20mPa・s(25℃))
  • Compatible with both heat- and photo-curing methods.

SUMITOMO SEIKA CHEMICALS suggest high refractive index monomer, utilizing organic sulfur compound synthesis technology.

Applications

  • For index matching
  • For improving light extraction efficiency
