Bentonite is naturally occurring hydrated Aluminum Silicate. The most important use of Bentonite is based on its natural swelling property. one can surely say that Bentonite is most economic natural thickener available to industries.
It has ability to absorb water several times its weight and give thick tropic fluid.
Chemically Bentonite is HYDRATED ALUMINUM SILICATE.

The greatest application of Bentonite is in oil drilling. Great quantities of Bentonite are used in drilling mud.
In paint industry it is used as a thickener in some cheap paints, primers, and water based coatings.
It is used in manufacture of cheap greases.
