Abstract:
The present invention relates to a method of producing a dispersion comprising a) mixing an aqueous dispersion of silanized colloidal silica particles with at least one organic compound containing at least two hydroxyl groups to provide an aqueous dispersion of silanized colloidal silica particles and said at least one organic compound, wherein the mixing is performed in the substantial absence of any monofunctional alcohol b) withdrawing water from the formed aqueous dispersion until the remainder of water in the dispersion is below about 10 wt %. The invention also relates to a dispersion obtainable therefrom and the use of the dispersion.
