ALBIPOX® F 081 is a high performance elastomer modified epoxy resins specially designed for composites with superior mechanical properties. By the modification with SiO₂ nanoparticles and elastomer components a three phase system is formed in the cured resin. Embedded in the continuous resin matrix are elastic domains (Micrometer size) and hard domains (Nanometer size), thus superior performance can be achieved. A cured resin compared with a similar unmodified resin exhibits various improved properties: Improved toughness (fracture energy, fracture toughness, impact resistance), Significant higher energy absorption at sudden mechanical impact, Superior mechanical properties at low temperatures, Improved adhesion to fabrics (glass, aramide or carbon fibres) and No reduced thermodimensional stability. Using ALBIPOX® F 081 toughened epoxy resin systems with excellent price/performance ratio can be formulated. ALBIPOX® F 081 are silicone-free, solvent-free and do not contain softeners. They are of medium viscosity, enabling their use in formulations for injection methods (e. g. RIM, RTM). The products can be used as delivered; depending on the respective application they can be blended with up to 50% standard epoxy resins. They are suitable for the combination with all epoxy resins, no restrictions or incompatibilities exist. All conventional epoxy hardeners can be used.
