Paints, Dyes and Polishes

Due to its thixotropic properties, bentonite and organic clays function as a thickening and/or suspension agent in varnishes, water and solvent-based paints. Its adsorption properties are appreciated for the finishing of indigo dying cloth, and in dyes (lacquers for paints & wallpapers).

Bentonite makes an excellent thickener for water base paints and coatings because of its suspending and thickening properties with pigments and extenders. Excellent thixotropy for reducing sags and drips. Bentonite provides low shear viscosity and prevent settling.

In the process of printing, some inks do not dry rapidly and cause blotting. A common cure for this problem is starch, held in suspension by a thin white bentonite suspension.
