Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-2-Ethyl(Pentadecafluoroheptyl)Sulfonylaminoethyl-.Omega.-Methoxy- is a high-performance fluorinated surfactant and surface modifier, distinguished by its unique perfluoroalkyl chain linked via a sulfonylaminoethyl spacer to a poly(ethylene glycol) (PEG) moiety. This molecular architecture provides exceptional surface tension reduction, thermal and chemical stability, and compatibility with both aqueous and organic systems. It is a critical raw material for formulators seeking to enhance the performance and durability of advanced coatings, fire-fighting foams, and specialty polymer processing aids. The CAS number for this compound is 68958-60-1.

Application

• Fluorinated Fire-Fighting Foams (AFFF/AR-AFFF): A key ingredient for generating stable, fast-spreading aqueous film-forming foams that effectively suppress hydrocarbon fuel fires.
• High-Performance Coatings and Inks: Used as a flow and leveling agent, wetting agent, and anti-cratering additive to improve substrate wetting and film formation in solvent-based and water-based systems.
• Polymer Processing: Acts as an internal and external lubricant and anti-static agent in the processing of engineering plastics and fluoropolymers to improve mold release and surface quality.
• Specialty Cleaning & Etching Formulations: Enhances the wetting and penetrating power of aggressive acid or solvent blends used in electronics cleaning and metal surface treatment.
• Oil & Gas Field Chemicals: Employed in formulations for gas suppression, anti-foaming, and as a component in drilling fluid additives where extreme conditions are encountered.
• Textile and Leather Treatment: Imparts oil, water, and stain repellency to fibers and finished goods without compromising breathability.

Quality Control

Every batch of our fluorosurfactant is produced and tested under a strict quality management system. We provide comprehensive Certificates of Analysis (COA) that detail key parameters such as assay (active content), water content, fluoride ion content, and pH. Our quality protocols are designed to ensure batch-to-batch consistency and performance reliability for your critical formulations. Certificates of Analysis (COA) are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture which may affect performance.
