Bentonite API Oman Drilling Mud Products Co LLC:

Less than 10 grams of bentonite if fully dispersed could cover a football field. It is a combination of these physical properties that make sodium bentonite an ideal waterproofing material. A layer of hydrated bentonite provides a dense low porosity barrier to fluid flow that exhibits a typical hydraulic conductivity of 1 x 10-9 cmsec.

What Are the Dangers of Bentonite:

Manufacturers use food-grade Sodium Bentonite to reduce the cloudiness of liquids such as wines and vinegars. Wine makers also use it as a sealant for wine barrels. Sodium bentonite works by exchanging its sodium atoms for other particles in a solution. This can lead to

Gunk Plug Squeeze Procedures Bentonite Diesel Oil:
