Description

Diammonium n-Ethylheptadecafluoro-n-[2-(Phosphonatooxy)Ethyl]Octanesulfonamidate is a specialized fluorinated surfactant and surface-active agent characterized by its unique combination of a perfluorinated alkyl chain and a phosphonate ester group. This molecular structure is engineered to deliver exceptional surface tension reduction, wetting, and leveling properties in challenging formulations. It is particularly valuable for industries requiring high-performance additives that are stable under extreme conditions of temperature and chemical exposure. Key users include manufacturers of advanced coatings, fire-fighting foams, and specialty chemical processing aids.

Application

• As a high-performance fluorosurfactant and leveling agent in industrial and decorative coatings, paints, and inks.
• As a key ingredient in aqueous film-forming foam (AFFF) concentrates for Class B fire suppression.
• As a wetting and spreading agent in electronic chemicals and precision cleaning formulations.
• As an additive to enhance surface properties and processing in polymers and plastics.
• As a specialty surfactant in oilfield chemicals for enhanced recovery and drilling fluids.
• In the formulation of metal treatment and plating baths to improve surface wetting and uniformity.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from incompatible materials such as strong acids and strong oxidizing agents.
