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