NANOPOX® HP 131 is a high performance, versatile, silica reinforced cycloaliphatic epoxy resin for the use in electrical/electronic applications, adhesives. and composites. The silica phase consists of surface-modified synthetic SiO2 nanospheres of very small size (average diameter of 20 nm) with a narrow particle size distribution (maximum diameter 50 nm). Despite the high SiO2 content of 40 wt%, NANOPOX® HP 131 has a comparatively low viscosity due to the agglomerate-free colloidal dispersion of the nanoparticles in the resin.
Typical Applications
NANOPOX® HP 131 is a versatile dispersion of colloidal silica in cycloaliphatic epoxy resin (EEC) for the use in various applications and markets. NANOPOX® HP 131 enables the combination low viscosity with high filler loading levels. It improves mechanical properties and fatigue performance even at cryogenic temperatures. It is transparent. Furthermore, NANOPOX® HP 131 can be cured thermally or cationically. Therefore it is frequently used in e.g. optical clear adhesives, medical application, stereolithography, underfill adhesives and conformal coatings.
