SURFACE-MODIFIED PARTICLES AND PRODUCTION METHOD

摘要

The invention relates to surface-modified particles, more particularly inorganic-based particles having reactive surfaces, more particularly surfaces containing silane-reactive and/or siloxane-reactive groups, preferably hydroxyl-containing surfaces and/or particles comprising or consisting of metal and/or semi-metal oxides and/or hydroxides, preferably nanoparticles, which on their surface have a polysiloxane-based modifier, having more particularly been reacted on their surface with a polysiloxane-based modifier, preferably with the formation of chemical bonds, more particularly covalent bonds, and also to a method of producing these surface-modified particles. The particles surface-modified in this way are suitable more particularly for use as fillers and/or for use in any of a very wide variety of systems, more particularly in dispersion systems, such as coating materials, for instance paints, inks and the like, and in dispersions of all kinds, in plastics, in foams, in cosmetics, such as in nail varnishes, for example, in adhesives, in sealants, etc.
