Talc (Soapstone) – Eshal Industries

Some of the important properties of Talc used in paint are colour, fineness of grind, oil absorption, chemical inertness and resulting viscosity. Talc helps to impart integrity, reinforce paint films control viscosity and prevent sagging of paint films. It improves suspension and prevents settling of solids at the bottom of the paint container.

Physical Properties of Talc & its Asbestos Content Talc or talcum is essentially a clay mineral made of hydrated magnesium silicate. The chemical formula for talc is H 2 Mg 3 (SiO 3) 4 or Mg 3 Si 4 O 10 (OH) 2. Some talc deposits also contain asbestos, so some talc products might also contain that material, depending on where the talc was mined.
