Transparent zinc oxide
Umicore Umicore is a specialty materials group which employs some 13.000 people, has industrial operations on all continents and serves a global customer base. Its activities are centered on four business areas : Advanced materials, Precious Metals Products and Catalysts, Precious Metals Services and Zinc Specialties. Each business area is divided into market-oriented business units. Umicore focuses on application areas where it knows its expertise in materials science, chemistry and metallurgy can make a real difference, be it in products that are essential to everyday life or those at the cutting edge of new technological developments such as nanomaterials. Umicore s overriding goal of sustainable value creation is based on this ambition to develop, produce and recycle metals in a way that fulfils its mission: Materials for a better life.
Umicore s nano zinc oxide umicore SEI 15.0kV X75,000 100nm WD 8.3mm Umicore has always pioneered new high tech solutions for its customers. ZANO is one of the latest solutions provided by Umicore. ZANO is a very homogeneous nano zinc oxide with a narrow particle size distribution, produced through Umicore s unique technology for nano materials. ZANO offers a very effective protection against the sun s harmful Ultra-Violet rays. Its UV-B/UV-A protection spectrum is much broader than that of the classical UV absorbers. Its narrow particle size distribution and small particle size lead to an excellent transparency in the different applications. Besides its combined UV-properties and transparency, ZANO exhibits the general properties of zinc oxide with its anti-bacterial and fungistat properties, its GRAS (generally regarded as safe) listing by the FDA in polymers, fibers, plastics and adhesives and the fact that it does not cause allergic reactions upon skin contact. Umicore does not only supply customers with industrial scale volumes of nano zinc oxide, but also supports customers with advice on material handling, quality control and characterization methods. Umicore is a real solutions provider: thanks to our R&D Department and strong collaboration with third parties we are able to develop tailor-made products for our customers, such as coated nano zinc oxide powders, stable dispersions in either aqueous or organic liquid media and doped nano zinc oxides. 100 100 Volume distribution 80 60 40 20 Transmittance (%) 80 60 40 20 broad spectrum UV blocker transparent in visible light 0 0 20 40 60 80 100 120 140 0 250 300 350 400 450 500 550 Particle size (nm) wavelength (nm) Particle size of a dispersion of ZANO 0,1 g/l ZANO aqueous dispersion
a broad range of applications Several ZANO qualities have been tailored depending on the application: ZANO 10 effectively protects the skin against the harmful rays of the sun in a broad range of cosmetic applications (sunscreens, daily skincare and hair-care applications, moisturizers, lip products, baby products). ZANO 20 offers long lasting broad spectrum UV-B/UV-A protection in transparent plastics and plastic films, as well as in textile applications. ZANO 30 is developed for clear coatings (wood coatings, floor coatings, lacquers, stains). Its exceptional incorporation in the clear coatings matrix brings about a unique long-lasting UV protection. Other applications include electronics, adhesives, inks, ceramics.
