In the competitive landscape of paint and coatings manufacturing, achieving optimal rheological properties is paramount. This directly impacts how a product is applied, its storage stability, and the final appearance of the film. Among the array of additives available, organic bentonite stands out as a highly effective rheological modifier. As NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier, we specialize in providing high-quality organic bentonite that empowers formulators to achieve superior results.

Organic bentonite, derived from montmorillonite clay, is chemically treated with quaternary ammonium compounds to make it organophilic, allowing it to disperse and swell in organic solvents and polymer systems. This interaction creates a microscopic network structure that imparts thixotropy – a shear-thinning behavior where viscosity decreases under agitation and recovers at rest. This characteristic is invaluable for applications like paints, inks, and adhesives, where ease of application (low viscosity under shear) is desired, followed by the ability to remain in place without sagging or settling (high viscosity at rest).

The benefits of incorporating organic bentonite into coating formulations are manifold. Firstly, it significantly improves anti-settling properties, preventing pigments and fillers from settling to the bottom of the container during storage. This ensures a uniform product and reduces the need for excessive remixing. Secondly, it enhances sag resistance, allowing for thicker film build without slumping, which is critical for achieving desired protective and aesthetic qualities. Furthermore, it can improve the overall mechanical properties of the dried film, such as hardness and resistance to solvents.

When selecting an organic bentonite, formulators must consider its compatibility with the specific solvent system and resin base. Many conventional organic bentonites, including our widely sourced products, require a polar activator (such as ethanol, methanol, or propylene carbonate) to fully delaminate and develop their rheological efficiency. The correct activation process is key to unlocking the full potential of these additives. Our technical team can guide you on the optimal dosage and activation procedures to buy and effectively utilize our products.
