摘要：A method of concentrating an aqueous dispersion comprising organic polymerparticles and silicon dioxide particles comprising the steps of: a) providing an aqueousdispersion comprising organic polymer particles and silicon dioxide particles, thedispersion having an initial content of organic polymers and an initial content of silicondioxide; b) contacting the dispersion of step a) with a creaming agent to yield an aqueousserum phase and an aqueous concentrated phase, and c) separating the serum phasefrom the concentrated phase. The invention further relates to a concentrated aqueoussilicon dioxide dispersion which is obtained by a method according to the invention and tothe use of such a dispersion as an adhesive.
