High refractive index coatings

Kriya’s High Refractive Index (HRI) coating is a medium solids, solvent based, UV curable, optical clear coating for plastic films. For glass,  it is an inorganic thermal curable coating. The Refractive Index (RI) can be tuned between 1.65 – 1.95. The coating can be used for various applications such as light in-/out-coupling, imprinting and RI matching for hiding ITO pattern and/or matching the RI in order to prevent iridescence patterns.
