Organoclay (Organobentonite, Quaternary Ammonium Bentonite)

Bentonite
CAS 68953-58-2

A quaternary-ammonium-modified bentonite engineered to thicken and stabilize non-aqueous, oil- and solvent-based systems. It functions as a rheological additive and thickener that imparts viscosity, sag resistance, and anti-settling behavior to solvent-based coatings, inks, greases, sealants, and oil-based drilling fluids.

Full Description

Organoclay (CAS 68953-58-2) is bentonite surface-treated with a quaternary ammonium compound to make it organophilic. It functions as a rheological additive and thickener that imparts viscosity, sag resistance, and anti-settling behavior to solvent-based coatings, inks, greases, sealants, and oil-based drilling fluids.

Frequently Asked Questions

What is organoclay used for?

Organoclay (CAS 68953-58-2) is a rheological additive and thickener that imparts viscosity, sag resistance, and anti-settling behavior to solvent-based coatings, inks, lubricating greases, sealants and adhesives, and oil-based and synthetic drilling fluids.

How is organoclay made?

It is produced by surface-treating bentonite clay with a quaternary ammonium compound, which exchanges onto the clay surface and makes the normally hydrophilic clay organophilic so it disperses and swells in non-aqueous systems.

What is organoclay thickener?

As a thickener, organoclay builds yield value and thixotropy in non-aqueous media, controlling sag and settling in coatings and inks and acting as a non-soap thickener in lubricating greases and a viscosifier in oil-based muds.

What grades and bulk packaging are available?

RawSource supplies organoclay in bags, drums, and bulk to coatings, ink, grease, and drilling-fluid manufacturers, with a CoA and SDS per shipment. Specify your application and volume for a bulk quote.

What is the cost of bulk organoclay?

Bulk organoclay pricing depends on grade, quantity, packaging, and freight. Send your application and target volume for a current landed quote; we do not publish a fixed price.
