It is not always possible to provide bentonite in desired properties with the reason that there is limited unmixed bentonite deposits in the world. Therefore, it is necessary to modify low-quality calcium bentonite with special additives for use of them in the market as an affordable bentonite.

Our product, which is convenient in terms of API 13A Part 9 specifications, is used to increase viscosity and reduce fluid loss in water based drilling fluids. Viscosity in freshwater and sea water muds is a cost effective method for fluid loss control and filter cake quality.


Bentonite is a clay mineral suitable in terms of API 13 A standards. It includes sodium and contains at least 90% montmorillonite. It contains special Karben Chemicals. It has high swelling capacity. It is also suitable in terms of TS EN 13500 Bentonite Specifications. It is suitable for TS 977 Type- 1 standards. It disperses easily when mixed with water and does not clump.
