NANOPOL® products are versatile dispersions of colloidal silica in solvents. The silica phase consists of surface-modified, synthetic SiO2 spheres of very small size (average diameter 20 nm) and very narrow particles-size distribution. Despite the very high silica content of up to 50 wt%, these products are highly transparent, low-viscous and show no sedimentation because the dispersion of the nanoparticles in the solvent is free of agglomerates. In formulations, a variety of properties, such as the following, can be improved:- increased strength and modulus
- increased hardness
- significantly improved fatigue performance
- synergy with conventional fillers
Application: NANOPOL® products are used in applications where silica nanoparticles can be added through the solvent route. Examples of possible uses for NANOPOL® products include the following:- impregnating solutions for pre-pregs for composites
- solvent or water-based adhesives
- applications in electrical and electronic equipment, (e. g., casting, potting, encapsulation)
