Features Of US Colloid VOLCLAY HPM 20 Bentonite Thickener

  1. High-yield, sodium-activated bentonite offering exceptional thixotropic control in water-based systems.

  2. Consistent rheology performance across varying pH and electrolyte concentrations.

  3. Low-dosage efficiency—delivers optimal viscosity and suspension stability at minimal loading levels.

  4. Free-flowing, dust-minimized powder formulation for safer handling and improved dispersion.

  5. USP-grade compliant raw material sourcing with rigorous quality control per ASTM D5558 and ISO 9001 standards.

Typical Applications Of US Colloid VOLCLAY HPM 20 Bentonite Thickener

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

  2. Drilling fluids for geotechnical and environmental borehole stabilization.

  3. Tile adhesives and cementitious grouts needing extended open time and vertical build.

  4. Fireproofing and intumescent coatings where controlled rheology ensures uniform application.

  5. Agrochemical suspensions and pesticide formulations requiring long-term particle suspension.
