OLED and LED Lights – Low Refractive index

Kriya’s Low Refractive Index (LRI) coating is a solvent based, inorganic, thermal curable coating with a refractive index (RI) as low as 1.35 for glass. For plastic, it is a solvent based, organic/inorganic, UV curable coating. It can be used in optical stacks to match the RI requirements in that specific construction. Combination with a hard coat or Antistatic hard coat as a base layer is possible and results in additional mechanical and/or antistatic properties. The LRI coating can be applied by standard wet coating techniques such as gravure and slot die.
