Abstract

Aqueous dispersions contain at least two chemically different particle types having a diameter on average of less than 100 μm. The dispersions are resistant to sedimentation and gelling for long periods of time, and can be used for many purposes, such as the polishing of optical surfaces, and in paints and adhesives.
