NanoArc® Zinc Oxide nanoparticles are available as coated dry powders wherein the material is treated to impart specific surface functionality to the particles, such as hydrophobicity.
The technology is designed for individual nanoparticle coating and as such prevents the formation of irreversible agglomerates.
The coating can be tailored to accommodate a range of surface functionality/reactivity, thereby providing the optimum compatibility with individual applications.
NanoArc® Zinc Oxide nanoparticles are available as concentrated (up to 50 wt%) dispersions in DI water. The aqueous NanoArc® Zinc Oxide dispersions feature proprietary surface treatment technology to enable formulation of the nanoparticles into systems ranging from pH 6 to 10.
The technology also ensures compatibility of the NanoArc® Zinc Oxide nanoparticles with aqueous formulations containing emulsion resins, both in-can and post-cure.
Dispersions of NanoArc® Zinc 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® Zinc 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® Zinc Oxide can be provided for specific solvent types or application needs (e.g. non-volatile liquids, plasticizers, etc.).
NanoArc® Zinc 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® Zinc Oxide nanoparticles into a wide variety of UV-cured coating formulations. The NanoArc® Zinc 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® Zinc 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.
