Kriya Materials has developed a line of optical hard coating products for the film and sheet industry. These optical coatings have specifically tuned refractive indices to meet the stringent requirements of the optical film industry in terms of optical clarity and prevention of rainbow effects.

Besides these functionalities the hardcoating products have high hardness and scratch resistance. The surface properties of the optical coatings can vary from non-overcoatable to overcoatable and printable, depending on the application.

The coating products are solvent based UV curable coatings comprising proprietry nanodispersions and are adapted for the processing technique as used by the end customer.
