3M scientists and researchers are exploring a new world at the nanometer level, where materials exhibit unique physical, chemical, and biological properties. These unusual properties are already being exploited in our hard coatings, dental restoratives, and brightness-enhancing optical films (used in LCD displays). Many 3M technology platforms, including adhesives and pharmaceuticals, are being influenced by the emergence of nano-sized particles.
3M builds its nanocomposite restoratives using a patented process that creates unique clusters of nanometer-sized particles. The nanoclusters wear at a similar rate to your tooth enamel, resulting in a smoother surface.
