First of all, organic bentonite and fumed silica have similar properties.
Their thickening and thixotropy are similar, but the difference is great. In waterproof coatings, meteorological silica has poor UV resistance and its yellowing index is much larger than that of organic bentonite. In the application fields of some silicone sealants, meteorological silica will be too strong in low-temperature thickening, reaching >6MPa, while the bentonite solution is less than 2.8Mpa.At the same time, the thixotropic index of organic bentonite is much higher than that of meteorological silica, which is generally between 4.2 and 5.0.

Organoclay Applications
Organic bentonite vs fumed silica
Organophilic Clay is an easy dispersing, self activating organoclay that exhibits high performance efficiency in diesel, low aromatic mineral oil, modified vegetable oil and synthetic base fluid formulation. CP-150 unique rheological structure suspends weighting materials and other solids with less increase in viscosity and gel strength than conventional bentonite. It is highly effective in distillate and mineral oil based invert fluids.
Organoclay Bentonite is used for Oil drilling Mud,
Paint,coatings, inks, grease and domestic etc.
Base oil:
- Diesel Oils
- Mineral Oils
- Synthetic Oil
- Linear and isomerized Alpha Olefins
- Modified vegetable oil
Viscosifying drilling Fluids:
- All oil based drilling fluids
- Invert emulsion fluids
- Workover fluids
- Fracture fluids
Organoclay Advantages
- Effectively suspends weighting materials and other solids
- Maintains suspension over a wide temperature range
- Eliminates need for chemical activators
- Is easy to disperse and rapid yielding
- Suspends weighting materials and other solids
- Maintains suspension over a wide temperature range
