Cationically stabilized aqueons silica dispersions, method for manufacture and use thereof.

It is provided a process for the preparation of cationically stabilized Silica described, wherein the silica in the form of an aqueous Dispersion or a powder by mixing cationic with an acid aminosilane solution is stabilized. By removal of the solvent, a cationic stabilized silica powder.The cationic obtained stabilized silica dispersion is very stable in storage. A mixture with organic binders such as PVA is no significant increase in viscosity possible. The dispersions are particularly suitable for coating colors for print media, such as ink jet paper, but also for the surface treatment of substrates, for example for hard coating of plastics, or release agents or Abrasives and polishing agents.
