Features Of American Colloid Company VOLCLAY HPM 75 Sodium bentonite thickener

  1. High-yield sodium bentonite with exceptional colloidal dispersion and suspension stability in aqueous systems.

  2. Optimized rheology profile for controlled viscosity build and excellent sag resistance in vertical applications.

  3. Consistent batch-to-batch performance due to proprietary purification and particle size control.

  4. Low soluble salt content, minimizing interference with sensitive formulations such as water-based coatings and drilling fluids.

  5. Readily dispersible with minimal mechanical shear, supporting efficient incorporation in industrial mixing processes.

Typical Applications Of American Colloid Company VOLCLAY HPM 75 Sodium bentonite thickener

  1. Water-based architectural and industrial coatings for improved anti-settling and brush/roller drag control.

  2. Non-aqueous and water-miscible metalworking fluids requiring stable emulsion and boundary lubrication support.

  3. Grouting and soil stabilization slurries where high thixotropy and low permeability are critical.

  4. Oilfield drilling fluid additives for borehole wall stabilization and fluid loss control in low-solids systems.

  5. Adhesives and sealants formulations requiring suspension of fillers and extended open time.
