With its outstanding properties, AEROSIL® fumed silica is used for laminating resins and gel coats as a thickening agent, for example in the in the automotive industry or in construction. For wind turbine rotor blades large quantities of bonding pastes are used. These bonding pastes must have good thixotropic und specific slump properties.
AEROSIL® fumed silicas are used as standard thixotropes in bonding pastes based on epoxy, polyurethane and vinylester resins. Hydrophobic fumed silicas are high-performance thixotropes used in bonding pastes for the manufacturing of rotor blades. Furthermore, bonding pastes must also possess excellent fatigue properties. Structure-modified fumed silica grades can adjust bonding pastes with excellent reinforcing properties.
