Super Hard nCoating for Multiple Substrates


NAMI has developed flexible, transparent super hard inorganic/organic hybrid coating materials – nCoating – for the application on flexible and rigid substrates, as well as in printing ink to improve surface hardness and scratch resistance.

Problem addressed

Currently, screen substrate materials used for flexible display are either plastic film, which is easily scratched, or ultra-thin glass which is easily broken. NAMI’s transparent nCoating is tough, yet flexible and highly adhesive, suitable for use in different areas including foldable screen, anti-smudge film, high hardness ink and anti-scratch wood.

  • NAMI's nCoating is a combination of organic-inorganic network structures with nano-size inorganic “glass” core surrounded by reactive organic “plastic” tails. Uniform dispersion of nano-size hard core and highly crosslinked plastic tails provides excellent anti-scratch hard surface and durable folding flexibility.
  • By optimizing the structural design and hence formulation, NAMI’s nCoating can be customized to super hard coating for various substrates. The glass-like hardness and plastic-like flexibility make it possible for foldable touch screen with super-hard anti-scratch surface and robust bending durability.
