Pixelligent offers standard and customized Zirconia (ZrO₂) and Titania (TiO2) nanocrystal dispersions using our PixClearProcess® services for prototype products, optimizing their surface chemistry and allowing seamless incorporation into various low-and-high boiling point solvents, monomers, and substrates to deliver revolutionary optical and mechanical properties when formulated. Pixelligent’s dispersions are compatible and crosslinkable with various acrylic UV-curable resin systems and can increase refractive index of base resins while maintaining low haze and high transparency. These materials can be used in optical and specialty coatings developed for applications including extended reality displays and optical sensors. PixClear® ZrO2 and TiO2 nanocrystals are available in both high-boiling (Propylene glycol methyl ether acetate) and low-boiling (Ethyl Acetate) solvents. Other solvents are available upon request. No aggregation or settling Long shelf life The viscosity of the solution increases with the loading of nanocrystals in solvents and monomers.
