High-yield sodium bentonite with exceptional colloidal dispersion and suspension stability in aqueous systems.
Consistent rheological performance across variable pH (6–10) and low-to-moderate electrolyte concentrations.
Optimized particle size distribution for rapid hydration and efficient viscosity development without excessive gel time.
Low soluble salt content, minimizing interference in sensitive formulations such as water-based coatings and drilling fluids.
Batch-to-batch reproducibility certified per American Colloid’s ISO 9001 quality management system.
Water-based architectural and industrial coatings for sag resistance and anti-settling performance.
Non-aqueous and water-miscible metalworking fluids requiring emulsion stabilization and boundary lubricity enhancement.
Oilfield drilling fluid additives for viscosity control, fluid loss reduction, and borehole wall stabilization.
Foundry mold washes and refractory binders where green strength and thermal stability are critical.
Adhesives and sealants requiring thixotropic structure to prevent slump during vertical application.
