Application

Thickener for aqueous and non-aqueous systems, clear films with grease resistance, binders, lubricants, steric stabilizer and water retention aid.

Features and Benefits

  • High-purity grade suitable for demanding industrial and research applications.
  • Offered in powder form easy to handle, measure, and dissolve, ensuring consistent dispersion in aqueous systems.
  • Propylene oxide content: 7 wt.% which improves film-forming and surface activity.
  • Low Molecular weight suitable for low viscosity formulations and improved mixing
Dissolves in water, undergoes reversible gelation upon heating, non-ionic, does not complex with ionic species and is surface active and enzyme resistant. Solutions are pseudoplastic.
