Abstract
The present invention relates to a method of producing an aqueous dispersion of silanized colloidal silica particles comprising mixing in an aqueous medium a) at least one silane compound containing an epoxy-functionality, b) at least one silane compound having no epoxy-functionality capable of modifying colloidal silica particles; and c) colloidal silica particles in any order to form an aqueous dispersion of silanized colloidal silica particles containing silane compounds originating from a) and b). It also relates to a dispersion obtainable by said method and to the use thereof in coating applications.
