Bentonite For Waterproofing

1. Sodium Bentonite
High swelling capacity

Excellent water absorption

Forms a gel-like consistency in water

Used in drilling muds, sealing ponds, and construction

2. Calcium Bentonite
Lower swelling properties

Better for absorption and surface bonding

Common in cosmetics, animal feed, and pharmaceuticals

â??ï¸? Key Properties
High water absorption

Strong binding capabilities

Thixotropic (gel-like when agitated)

Chemical stability

Thermal stability

Cation-exchange capacity

Export-ready documentation

Bentonite is a highly colloidal clay mineral which gets its name from the place where its presence and usages were first discovered - Fort Benton, America. The multiple properties of bentonite namely hydration, swelling, water absorption, viscosity, thixotropy make it a multi-application product for diverse industries.

Primarily two varieties of bentonite are available - sodium bentonite (high swelling, gelling and thermal durability) and calcium bentonite (more commonly available worldwide but with less swelling).

Bentonite has high swelling properties along with good viscosity and liquid limit. These properties are highly valued in most of the industrial applications. Sodium bentonite is well suited as a binder in the preparation of pellets, and in foundry and oil - well drilling mudSodium-based bentonite of 75 mm size finds suitability in iron ore pelletisation for bonding by user industries. Bentonite has also remarkable colloidal and waterproofing properties.

Chemical formula :- Al2H2Na2O13Si4

Application :
Bentonite is also used in chemical, rubber, insecticide & pesticide industries and in civil construction works.

Bentonite in the form of fine powder free from dirt and other foreign matter and of least swelling property is used in ceramic industry.
