Organic bentonite vs fumed silica

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.

The organic bentonite vs fumed silica comparison is a key formulator decision: organic bentonite offers superior thixotropy in high-polarity solvents, while fumed silica performs better in very low-polarity systems; for organic bentonite product specifications, see organoclay — organic bentonite rheology modifier specifications. The classification of both within the rheology modifier family is covered in rheology modifiers — organic bentonite vs fumed silica classification.
