Background

Nanophase Technologies is an industry-leading nanocrystalline materials innovator and manufacturer with an integrated family of nanomaterial technologies. The entire focus of Nanophase is nanotechnology, with two distinct and patented processes for the preparation and commercial manufacturing of nanopowder metal oxides i.e. Aluminum Oxide, Zinc Oxide, Cerium Oxide, Titanium Dioxide, and several others. Nanophase Technologies Corporation has developed a process, Discrete Particle Encapsulation, to coat the surface of its nanoparticles with a thin polymeric shell that enables compatibility of the particles with a wide variety of fluids, resins and polymers. Also, Nanophase has developed technology to permit the dispersion of its nanoparticles in water and a variety of polar and non-polar organic fluids. This allows Nanophase to supply concentrated, ready-to-use nanoparticle dispersions, eliminating the need for customers to disperse the nanoparticles themselves. Nanophase’s family of integrated technologies economically produces nanocrystalline materials, and then nanoengineers those materials to fit a customer need.

Applications and Markets

Nanophase produces engineered nanomaterial products for a variety of diverse markets: personal care, sunscreens, abrasion-resistant applications, environmental catalysts, antimicrobial products, and a variety of ultra-fine polishing applications, including semiconductor wafers, hard disk drives, and optics. Various applications include wood preservation, anti-fouling and anti-microbial coatings, fuel cells, catalytic converters, UV-attenuation coatings, scratch resistant coatings, charge dissipating coatings, deodorant/antiperspirants, depilatory/shaving products, and others. In parallel, new markets and applications are constantly being developed.

Abrasion-Resistant Coatings

The incorporation of nanomaterials in surface coatings can provide long-term abrasion resistance without significantly effecting optical clarity, gloss, color or physical properties. The need for scratch, mar and/or abrasion resistance is well established in various markets, including fingernail polishes, flooring, plastic glazing, headlamp covers and other automotive parts, transportation windows and optical lenses, where clear scratch-resistant coatings are used.

NanoDur Alumina

NanoDur alumina is especially well-suited for incorporation into coating systems, greatly enhancing abrasion resistance with minimal effects on clarity, gloss and physical properties of the coatings. The NanoDur products can also be surface treated through proprietary technology to ensure compatibility with a variety of coating systems.
