Description

Bis(2-Hydroxyethyl)Ammonium Perfluorooctanesulfonate is a fluorinated surfactant salt known for its exceptional surface activity and chemical stability. This compound is valued for its ability to dramatically lower surface tension in aqueous and non-aqueous systems, even at very low concentrations. It is a critical material for industries requiring high-performance wetting, leveling, and anti-foaming agents, particularly in demanding chemical environments.

Application

• As a high-performance surfactant and wetting agent in specialized coatings, paints, and ink formulations.
• As a leveling and anti-cratering additive in high-end industrial and electronic coatings.
• As a key ingredient in fire-fighting foams (AFFF) due to its fluorosurfactant properties.
• As a surface treatment agent for textiles, leather, and paper to impart oil and water repellency.
• As a emulsifier and dispersion aid in the polymerization of fluorinated monomers.
• In specialty cleaning formulations and etchants for the semiconductor and electronics industries.
• For research and development of novel fluorinated materials and surfactants.

Quality Control

Our production of Bis(2-Hydroxyethyl)Ammonium Perfluorooctanesulfonate adheres to strict internal quality standards to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed for critical parameters including purity, identity, and moisture content. A comprehensive Certificate of Analysis (COA) documenting these results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance and handling.
