Because of its shape, platy talc can have a beneficial effect on paint rheology. It generally contributes to improved brushability, leveling and sag resistance. It is normally self-suspending in paint vehicles and assists in keeping other pigments suspended. When settling does occur, it is generally soft and is readily redispersed.

Talc The term talc covers a wide range of natural rocks and minerals, most of which are magnesium silicates. Talcs tend to form in plates. You can see the platy nature of talc from this Scanning Electron Micrograph (SEM) taken at a 5,000 times magnification. This platy structure gives talc many of its reinforcing performance properties in plastics.
