Organo clay Rheological Additive

In the process of producing and selling organic bentonite Organo clay Rheological Additive for more than 20 years, we have always insisted on producing high-quality organic bentonite to satisfy users with regard to the performance of the entire formula in terms of rheology control.

  Rheological Additive Advantage

• Good sag resistance

• Increases anti settling ability in paint  (Prevents pigment Settling)

• High thixotropy when anti settling agent in paint (Solvent based paints)

• Confers temperature stability 

• Imparts particle suspension

We have been continuously researching and developing the performance of anti-settling performance, anti-sag performance and suspension performance. We can say with certainty that if you need to achieve the rheological properties of suspension, thixotropic properties of thickening, etc. in the formula, , our organic bentonite can meet your needs in these aspects.

What are rheological additives?

Organo clay Rheological Additive

Bentonite has been modified to become a thickening rheology agent, which has the properties to control rheological properties. At the same time, it is very superior in thixotropic properties, so many paint and coating manufacturers choose our organic bentonite.

Its biggest feature is that it has relatively good gelling properties and is easy to disperse. If you do pre-gelling, its effect will be even better in terms of performance. During this process, we recommend that you add a polar activator, such as water, methanol, ethanol, but our most recommended is propylene carbonate. It can promote the full performance of each performance.

It is also very important to use organic bentonite as a step in the entire formula, because if it is added in the wrong order, it will affect the compatibility with other raw materials.

Rheological additive uses

It has an extremely wide range of applications. In addition to the inks and paints we mentioned above, it can also be used in cosmetics. Currently, in cosmetics, we mainly use it in nail polish and lotion. Because organic bentonite has an effective preliminary effect and has thickening rheological properties, many cosmetic companies like to use this product.

Regarding the use of additive amounts, we hope you can draw conclusions through practice, because the final results you want to obtain in terms of matching performance of different formulas depend on your dosage.
