Talc is a natural mineral powder of magnesium silicate. This pigment is found as a combination of lamella and fibres. The fibre part strengthens flexibility of paint film and its lamella part increases the paint resistance against water penetration.  A large percentage of the world’s manufactured talc is used as a filler and extender in the paint industry. Important properties of talc includes softness, good diffusion co-efficient, neutrality against solutions and low weight. Talc micronized powder is white and has a high luminosity, which makes it a great filler in the paint industry. This filler improves and stabilizes the outer surface of object and controls the concentration and properties such as luster and veneer and in addition reduces the cost of production. In general, talc powder is very effective in uniformly spreading, preventing loosening paint layers, smoothing and has oil absorption power.

     Most paints are suspension of mineral particles in the liquid. The liquid part of the paint facilitates its application. But after the liquid evaporates, the mineral particles remain on the wall. The sheet-shaped particles of the talc improve the solid suspension in the can and help the adhesion of liquid paint to the wall without being bulky. The low hardness of talc is advantageous because it causes less abrasion and less damage on paint spray nozzles and other painting equipment.
