Features Of US Colloid VOLCLAY Rheospan Bentonite Thickener

  1. High-yield, sodium-activated bentonite delivering exceptional rheological control in water-based systems.

  2. Consistent thixotropic behavior with rapid recovery after shear, ensuring stable suspension and sag resistance.

  3. Low-solids formulation enables high-performance thickening without excessive viscosity buildup or gelation.

  4. Excellent compatibility with common surfactants, dispersants, and electrolytes across diverse formulations.

  5. Batch-to-batch reproducibility supported by stringent raw material sourcing and QC testing per ASTM D5558.

Typical Applications Of US Colloid VOLCLAY Rheospan Bentonite Thickener

  1. Water-based architectural coatings and industrial paints requiring anti-settling and spray-applied rheology.

  2. Oilfield drilling fluids where controlled yield point and low-end rheology are critical for cuttings transport.

  3. Tile adhesives and cementitious grouts needing extended open time and non-drip application properties.

  4. Agrochemical suspensions to maintain active ingredient homogeneity during storage and field application.

  5. Fire-retardant intumescent coatings requiring stable, high-solids dispersion without premature settling.
