Organo-modified bentonite | organically modified bentonite
Organo-modified bentonite is an organically Bentonite), derived from a naturally clay mineral. The main component is bentonite, montmorillonite clay.
Organo-modified bentonite include solvent base organoclay and water based organoclay.
as a component in paint formulations or as a OBM viscosifier for oil-based drilling fluids. Organophilic bentonite clay can be used in polymer chemistry as a suspending agent.
Organophilic bentonite clay is an organic bentonite clay act as Rheological additive in low to high polarity systems.
Such as Ketones, Glycol and Ethers, Alcohol, Esters includes Polar System with some Aromatic Solvents.
- Drilling Fluids : Organoclay bentonite as an suspending agent. It is used in drilling muds in the world. They are used to suspend the heavy sealing agents.
Organoclay bentonite can also be used in fracturing( fracfluids), where the organoclay gelling ability of them is used to seal rock fractures in the bore hole.
- Paints & Coatings : A small addition of Organophilic bentonite clay can greatly enhance the rheological properties of the paint system.
The properties of organoclay include prevent pigment settling and sagging on vertical surface to ensure the thickness of the coating .
They also ensure good leveling.
Organoclay bentonite are used widely in a wide range of solvent based paint systems.
- Industrial Coatings : Organoclay bentonite could use for air drying, Epoxies, Esters, Urethanes, Vinyls, Acrylics, Anti-Corrosive, Coil, Road Marking, Underbody Car Coatings and Nitro Cellulose .
- Printing Inks : Choose correct Organoclay bentonite could adjust the consistency of printing inks to get the ideal performance.
avoiding pigment settling and sagging, providing good color distribution obtaining desired thickness.
Organoclay bentonite are used in much letter press ink, lithographic and offset ink.
- Lubricating Greases : Thickening lubricating oils with Organoclay bentonite can produce specialty high temperature resistant lubricating greases.
Organoclay bentonite also gives good working stability and water resistance to the greases.
