CEMBEN CEMENTING BENTONITE It is a natural Sodium Bentonite confirms to API 13 A Section 10. It is Viscosifier and Filtration control agent for water based Mud Systems. It is used in drilling muds for controlling bore hole stability. It is utilized in drilling muds to extract drill cuttings from the bit.


• It is compatible with all cement slurries & cement additives. • It helps improve hole cleaning capacities of drilling fluids.
• It is effective as a filtering agent.
• It promotes borehole stability.

• It can be added directly to fresh water or fresh water based drilling fluids. 

• Fast and easy mixing and Reduces solids / increases lifting power
• Removes cuttings, Cools and lubricates bit
• Stabilizes boreholes and Helps prevent loss of circulation


Treatment rates will vary depending on the desired rheological properties. The level of water purity will affect bentonite performance. For best results, add through a jet / hopper mixer.
