Recently developed nanotechnological reinforced composites consisting of monodisperse, non-agglomerated SiO_2-particles and radiation-curing resins (unsaturated acrylates and cationic curing epoxies) show a great enhancement of scratch and abrasion resistance, toughness and hardness without possessing the disadvantages known from other inorganic additives. Even with loads of silica up to 50%, water-clear products with low viscosities and no sediment-formation are realized, making these nanocomposites a useful and versatile raw-material source suitable for all kinds of high performance applications.
