Uzwil, May 11, 2010 – The Buhler Group is making selected dispersions of inorganic nanoparticles accessible worldwide to materials science researchers through an exclusive distribution agree-ment with Sigma-Aldrich.
Buhler and Sigma-Aldrich® (Nasdaq: SIAL) have signed an agreement in which research volumes of nanoparticle dispersions from Buhler will be sold worldwide exclusively by Sigma-Aldrich. These prod-ucts are dispersions of nanoscale inorganic particles in water and organic solvents, which show great economic potential in a wide spectrum of possible applications. The initial target group for these prod-ucts will be materials science research and development. The dispersions are manufactured in the nanotechnology business unit (PARTEC) of the Buhler Group and are sold worldwide through the Al-drich® Materials Science initiative of Sigma-Aldrich.
The agreement covers dispersions of nanoscale titanium dioxide (TiO2), zinc oxide (ZnO) and hydrated iron oxide (FeOOH). Dispersions of nanoscale titanium dioxide in water, xylene and a mixture of ethyl-ene glycol open up development options for the photocatalytically active semiconductor material in such diverse fields as solar energy, printed electronics, and self-cleaning and superhydrophilic surfaces. Dispersions of hydrated iron oxide are available in water and ethanol. Dispersions in water, ethanol, butyl acetate and butyl glycol provide a wide solvent polarity spectrum for researching applications of the nanoscale zinc oxide. Zinc Oxide is already being used in UV absorbers and as a fungicide in coat-ings, and as a ceramic for electronic components such as varistors.
