NanoArc® Aluminum Oxide nanoparticles are available as concentrated (up to 50 wt%) dispersions in DI water. The aqueous NanoArc® Aluminum Oxide dispersions feature proprietary surface treatment technology to enable formulation of the nanoparticles into systems ranging from pH 4 to 10.
The technology also ensures compatibility of the NanoArc® Aluminum Oxide nanoparticles with aqueous formulations containing emulsion resins, both in-can and post-cure.
In addition, untreated NanoArc® Aluminum Oxide is available as a low pH (< 5) aqueous dispersion for applications not requiring the compatibility surface treatment.
Dispersions of NanoArc® Aluminum 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® Aluminum 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® Aluminum Oxide can be provided for specific solvent types or application needs (e.g. non-volatile liquids, plasticizers, etc.).
NanoArc® Aluminum Oxide nanoparticles are available as concentrated (30 wt%) dispersions in low viscosity acrylate monomers such as TPGDA (tripropyleneglycol diacrylate) and HDDA (1,6-hexanediol diacrylate).
These dispersions can be used to incorporate NanoArc® Aluminum Oxide nanoparticles into a wide variety of UV-cured coating formulations. The NanoArc® Aluminum Oxide nanoparticles are surface treated for compatibility, and do not interfere with the radiation cure process of the coatings.
Other low viscosity acrylate monomer dispersions of NanoArc® Aluminum Oxide are also available on a custom basis.
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.
