NANOPOL® A 720

1 of 3 products in this brand
NANOPOL® A 720 is a flexible dispersion of colloidal silica in n-butyl acetate solvent. The silica phase is composed of surface-modified, synthetic SiO₂-spheres that are very small in size (Ø 20 nm) and have a narrow particle size distribution. Despite having a high SiO₂-content of 50 wt%, NANOPOL® A 720 is transparent, low in viscosity, and does not show sedimentation due to the agglomerate-free dispersion of the nanoparticles in the solvent. It significantly improves tear resistance, fracture toughness, and modulus. NANOPOL® A 720 can be used to formulate highly filled, transparent adhesives based on various reactive resins. It is also easy to process due to its uncritical solvents.
