Title: Surface-modified silica gels

Abstract: The invention relates to surface-modified silica gels, to a process for preparing them, and to their use as matting agents in coating materials. As a result of the nature of the surface modification, the viscosity of 2-component coating materials is increased only slightly, or not at all, after the matting agent has been added.
