Talc in Paints & Coatings

Talc Powder of Avani Group of Industries is the powdered form of Magnesium Silicate. Dolo-Talc Powder of Avani Group of Industries is a blend of Talc and Dolomite minerals. Talc and Dolo-Talc possess several physical and mechanical properties which uniquely suit Paints and Coatings. As a result, both decorative paints and industrial coatings use Talc and Dolo-Talc powder in their manufacturing:

  • The lamellar (platy and layered) structure of talc reinforces paint films by preventing sagging and improving adhesion. This, in turn, prevents cracking and peeling of the paint from walls.
  • Also, the paint spreads across any surface in an even layer by covering any gaps or pores because of the lamellarity of Talc.
  • Since Talc is hydrophobic and opaque, it improves water-repulsion and weather resistance of paints and coatings. Furthermore, Talc provides the benefit of UV protection.
  • Considering that Talc is both opaque as well as high in brightness, it covers up any spots or discolouring of the underlying material and accentuates the colour of the paint.
  • Talc as an extender, increases viscosity of the paint. Subsequently, this facilitates easy and comfortable dispersion of paint.
  • Automobile or industrial powder coatings and paints have finely micronized particles. This property makes the resulting paint easily sprayable. Due to its softness, Talc is readily micronized and fills up even the smallest of spaces when metallic surfaces are sprayed with powder coatings and paints.
  • Because of its soft and chemically inert nature, talc contributes minimal abrasion to the vessels and the applicator.
  • Manufacturing process of wall-putty requires ingredients which are rich in lime (CaCO3) and also have high oil absorption capacity. This requirement makes Dolo-Talc an ideal contender because of lime-rich Dolomite and oil-absorbing Talc in its composition.
