The characteristic of not requiring pre-gelation treatment makes organic bentonite far superior to traditional clay thickeners in terms of ease of use.
In traditional processes, bentonite must be soaked in an activator for several hours to form a gel mother liquor, with strict control of temperature and stirring speed; even minor deviations can result in uneven dispersion.
In contrast, organoclay bentonite can be directly added to base oil and preliminarily dispersed by stirring for 5–10 minutes at room temperature, eliminating the need for complex pre-gelation steps.
A case study from a medium-sized lubricant manufacturer shows that adopting this process reduced the production workflow from 8 steps to 5, shortened processing time by 40%, and cut equipment investment by 50% (no dedicated gel preparation tanks required).
Additionally, the direct addition method minimizes human operational errors, boosting product pass from 85% to 98%, making it particularly suitable for small-batch, multi-variety production needs.
Organoclay for Grease
Organophilic clay CP-720A is a kind of purified and modified organoclay rheological additive, designed especially for using in Grease based on synthetic oils such as vegetable oil, polyester oil. Organic clay has high gelling efficiency, fine thixotropy and perfect anti-settling.
Organiclay bentonite CP-720A is used in the following applications:
Advantages of Organoclay Rheological Additive
Properties of Organoclay adhesives for metal
Composition Organic derivative of a montmorillonite clay
Appearance Fine powder, light yellow
Moisture content (105℃,2hr) ≤3.5%
Loss on ignition (1000℃) 34%-36%
Bulk density 0.42g/cm3
Fineness (<74μm, %) ≥98%
Organobentonite Packages
Kraft paper bag with PE liner or multi-wall paper sacks or customized. 25kg/bag or 22.68kg/bag or customized.
Organophilic clay Store in a dry, well-ventilated area with temperature of 0℃-30℃. Keep container closed. The quality guarantee period is 24 months.
Organoclay adhesives for metal
When it is used in Grease Lubricant, polar activator is needed. Polar activator is acetone/water(95/5). The dosage of activator is 20%-30% of the weight of CP-720A. And also high shear can promote the dispersing of rheology modifier CP-720A.
Adding procedure as follows:
Note: With High-speed dispersant of grinding machine, and properly prolong the dispersing time, better gelatin performance can be reached.
The Lubricanting grease which uses organoclay as thickener will own high dropping point, thus can be used under high temperature and presents good impermeability and water resistance.
