Organic bentonite clay has been produced and applied in China for more than 30 years.It is the complex of montmorillonite/quaternary ammonium salt produced from the raw bentonite. Bentonite’s main ingredient: montmorillonite which has layer structure. There is a net nagetive surface charge on the bentonite, inorganic cations can be replaced by organic cations forming organic bentonite clay. Organic bentonite clay can form gel when meet various organic solvents, oil and liquid resin. Organic bentonite clay can be widely applied in various systems to increase viscosity, provide thixotropy, prevent pigment settling during storage, improve flowing and leveling, improve high temperature stability, lubricating property, film forming property, water resisting property and chemical stability. Also it can be applied in coating and painting industry, lubricating grease, ink industry, oil drilling industry, polymer materials industry and so on. Organic bentonite clay can be used in solvent-based systems as thickening agent, suspending agent, thixotropic agent and stabilizer.
