FIELD: chemistry.
SUBSTANCE: invention can be used in paint industry. The method of producing an aqueous dispersion of silanised colloidal particles of silica in an aqueous medium involves mixing a) at least one silane compound with epoxy functionality, b) at least one silane compound without epoxy functionality, capable of modifying colloidal particles of silica, and c) colloidal particles of silica to form an aqueous dispersion of silanised colloidal particles of silica containing silane compounds from a) and b). The weight ratio of a) and b) to silica ranges from about 0.01 to 1.5.
EFFECT: invention increases stability of colloidal silica dispersions, water resistance and hardness of lacquer coatings.
