Tiny particles, huge effect: Radiation curable silica nanocomposites for scratch and abrasion resistant coatings

Nanotechnological reinforced composites consisting of monodisperse, non-agglomerated SiO 2 -particles and radiation-curing acrylic resins show a great enhancement of scratch and abrasion resistance 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.
