Adhesivos y sellantes. Replacement of fumed silica In a polyurethane adhesive I am using a hydrophilic fumed silica like AEROSIL R 200 or Cab-O-Sil M5 to adjust the rheological behaviour. Is there a chance to replace a certain amount of fumed silica and to avoid the viscosity drift during storage time.
