Organophilic Bentonite (Organoclay)

It builds thixotropic structure: viscosity at rest that breaks down under shear and recovers afterwards. In coatings and inks that means anti-settling of pigment and anti-sag on a vertical surface; in adhesives, sealants and greases it means shape retention and consistency; in oil-based drilling fluids it means suspension and gel strength. Addition level and performance are established on your own material and equipment, because supplier literature values are starting points for a trial and not a specification.

The carrier system decides almost everything: the polarity of the solvent or oil, whether a polar activator is used, and the dispersion energy available in your process determine which modification and which presentation will develop structure at all. State the system, the shear available, the process temperature, the sag, settling or thixotropy behaviour you need, and the addition range you are working within.

Untreated sodium bentonite and calcium bentonite are water-side materials and are separate canonical records on this catalogue; organophilic bentonite performs in organic media and is not interchangeable with either. It is also not the same as fumed silica, which is an alternative rheology route in some systems but a different material with its own page. Different quaternary modifications, particle presentations and self-activating versus activator-requiring types are grade dimensions handled inside this record.

Suppliers report particle size in different conventions — mesh, percentage passing a stated mesh, micron top cut, or D50 from a named measurement method — and the numbers are not interchangeable between conventions. State the convention your specification uses, along with the property window you actually need, and comparison is made like for like. Moisture, pH, bulk density, swelling behaviour, heavy metals and any documentation requirement are reviewed the same way, against producer data for the grade offered.

This page asserts no purity, assay, mesh, micron, D50, brightness, swelling capacity, moisture, pH, bulk density, surface area, heavy-metal limit, origin, mine, packing, minimum quantity, certification, approval, availability, lead time or price. Every commercially meaningful value is taken from producer documentation for the exact grade offered and confirmed in writing before order.

Allzone sources this material through producer channels and quotes it per enquiry. Origin, mining location and processing location are selected against your technical requirement, quantity, documentation need and destination, and are stated in the offer rather than fixed by this page. Mineral powders have low value density, so freight, discharge point and packaging format move landed cost as much as the material price; quotations are compared delivered to your plant.

Technical data sheet, safety data sheet and certificate of analysis for the exact grade offered are requested from the producer and shared with the quotation. Mineral powders create airborne dust during transfer and bagging, and respirable crystalline silica content varies by material and by grade, so it is treated as an SDS and workplace-controls question for the specific grade rather than a figure published here. Where a declaration matters to your application — food contact, feed, potable water, cosmetic or regulatory — it is confirmed for that grade and intended use rather than assumed from this page.

Send the material or system it goes into, the process it runs on, the function you need it to perform, the property window your specification calls for in your own convention, the annual and per-shipment quantity, the packaging format your intake can receive, the documentation required per shipment and the delivery province or port. Several materials can be listed in one enquiry and reviewed together rather than split into separate requests.
