Nanotechnology at BASF: a great future for tiny particles

Published on 2002-12-03. Author : SpecialChem

 

Nanotechnology is a truly cross-sectional technology both from the scientific viewpoint and because of its myriad possible applications - in chemistry and beyond. Particle size, or more accurately tininess, is the common feature of all nanoproducts and varies from one to several hundred nanometers. A nanometer is the millionth part of a millimeter, or about 50,000 times smaller than the diameter of a human hair.

BASF is conducting research into the characterization and production of new nanomaterials. These materials are usually integrated into products to improve their performance profile or create completely new properties.

Aqueous polymer dispersions are not only a remarkably versatile class of products, but also one of BASF's greatest strengths. BASF's annual sales of these products amount to around EUR1.5 billion. All of them contain polymer particles ranging from ten to several hundred nanometers in size. Polymer dispersions are found in exterior paints, coatings and adhesives or are used in the finishing of paper, textiles and leather.
