Nano zirconia acrylic dispersion for refractive index adjustment of optical materials

Release time:

2023-08-21

Nano zirconia is characterized by high hardness, high temperature resistance, chemical resistance, abrasion resistance, low thermal conductivity, strong thermal shock resistance, good chemical stability and outstanding material composability.

The nano-zirconia acrylic dispersion developed by Winlight Optics is a dispersed and homogenized nano-zirconia acrylic dispersion, soluble in organic solvents. Acrylic monomer is used as the dispersing medium; nanosized zirconia particle size is small and uniformly distributed, good compatibility with organic solvents/resins; it can be used for cell phone brightness enhancement film, OLED light extraction and other optical materials refractive index adjustment purposes.
