Features Of US Colloid VOLCLAY HPM 75 Bentonite Thickener

  1. High-yield, sodium-activated bentonite with exceptional rheological control in aqueous systems.

  2. Consistent thickening performance across variable pH (6.5–10.5) and low-to-moderate electrolyte concentrations.

  3. Excellent suspension stability for insoluble solids in coatings, sealants, and construction slurries.

  4. Low-dust, free-flowing granular form designed for simplified handling and dust-minimized blending.

  5. Non-toxic, non-hazardous formulation compliant with major industrial safety and environmental guidelines.

Typical Applications Of US Colloid VOLCLAY HPM 75 Bentonite Thickener

  1. Water-based architectural and industrial coatings requiring sag resistance and anti-settling properties.

  2. Cementitious grouts and tile adhesives where viscosity build and thixotropy are critical for vertical application.

  3. Oilfield drilling fluid additives for low-solids, high-performance bentonite-based viscosifiers.

  4. Foundry mold washes and refractory coatings needing stable suspension of high-density fillers.

  5. Adhesives and mastics requiring controlled open time and non-drip rheology during application.
