In standard coating processes involving powder layering, Colloidal silicon dioxide is used to facilitate powder build-up in the coating while also helping maintain pigments in suspension.

Thus, in the strictest sense, the term colloidal silica applies to stable dispersions (or sols) consisting of discrete particles of amorphous silica having sizes of between 5 and 100 nm.
