Nanotechnology is the ability influence materials at the atomic level to create configurations that have unique properties and characteristics because of their size, shape and/or structure. A nanometer is one billionth of a meter, which is approximately 100,000 times smaller than the width of a human hair. At the nanoscale, these properties can be fundamentally different than the properties of the same materials at a larger scale. When nanostructures are engineered into end user chemical products, these products benefit from enhanced uniformity, durability, bonding and adhesion and longevity. SEI's Mold, Graffiti, Corrosion and Coatings lines employee nanoparticulates that provide leading-edge performance characteristics.
