Aqueous Dispersions

NanoArc® Cerium Oxide nanoparticles are available as concentrated (up to 50 wt%) dispersions in DI water as either untreated particles, or as particles stabilized with proprietary surface treatment technology. The non surface-treated NanoArc® Cerium Oxide aqueous dispersions are stable at low pH (< 5).

Surface-treated aqueous NanoArc® Cerium Oxide dispersions enable formulation of the nanoparticles into systems ranging from pH 4 to 10. The technology also ensures compatibility of the NanoArc® Cerium Oxide nanoparticles with aqueous formulations containing emulsion resins, both in-can and post-cure.

Solvent Dispersions

Dispersions of NanoArc® Cerium Oxide nanoparticles are available as concentrates (up to 50 wt%) in polar hydrocarbon solvents such as PMA (propylene glycol methyl ether acetate), nonpolar solvents such as mineral spirits, and protic solvents such as alkoxyethers.

The NanoArc® Cerium Oxide dispersions feature surface treatment technologies designed specifically for the solvent class, and tailored to be compatible with a wide range of application formulations employing solvents in these classes. In addition, custom dispersions of NanoArc® Cerium Oxide can be provided for specific solvent types or application needs (e.g. non-volatile liquids, plasticizers, etc.).

Custom Dispersions

Nanophase metal oxide nanoparticles are available in a variety of concentrated dispersion forms, each featuring proprietary surface treatment technology to ensure complete dispersion to the primary particles and to prevent any aggregation upon incorporation into application systems.
