High viscosity grade offering excellent thickening and suspension performance in aqueous systems.
Outstanding thermal gelation profile with reversible gel formation above ~60 °C, ideal for controlled-release applications.
Excellent water retention capacity, enhancing workability and reducing cracking in cementitious and plaster formulations.
Consistent batch-to-batch reproducibility ensured by Ashland’s stringent GMP-aligned manufacturing controls.
pH-stable across broad range (3–11), maintaining performance in acidic or alkaline environments without degradation.
Cement-based tile adhesives and grouts requiring extended open time and sag resistance.
Self-leveling underlayments where high flowability and anti-settling behavior are critical.
Pharmaceutical immediate-release tablets as a binder and dry granulation aid.
Water-based architectural coatings for rheology control and spatter resistance.
Oilfield cement slurries to improve fluid loss control and slurry stability at elevated temperatures.
