Process for the preparation of dispersions with nanoscale silica particles of fumed silicas

摘要

The present invention relates to a method for producing a dispersion with nanoscale silicon dioxide particles from pyrogenic silicas in a paint binder with the following process steps: (1) initially at least one oligomeric and / or polymeric siloxane compound in at least one liquid paint binder with at least one reactive thinner, ) Dispersing in at least one fumed silica while stirring, (3) stirring the dispersion until a constant viscosity is reached.
