Description

9,9,10,10,11,11,12,12,13,13,14,14,15,15,16,16,17,17,17-nonadecafluoro-3-(2-hydroxyethyl)-5-[(3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,11-nonadecafluoroundecyl)oxy]-4,6-dioxa-3-aza-5-phosphaheptadecan-1-ol 5-oxide is a highly fluorinated, phosphorus-containing specialty surfactant designed to impart exceptional surface-modifying properties. This compound is engineered to deliver superior oil and water repellency, low surface energy, and chemical resistance in demanding formulations. It is a critical performance additive for industries requiring advanced surface treatments, including high-performance coatings, specialty textiles, and fluoropolymer processing.

Application

• Fluorinated Surfactant & Leveling Agent: Used in high-performance industrial and architectural coatings to improve wetting, leveling, and substrate adhesion while reducing surface defects.
• Oil & Water Repellent Finishes: A key ingredient for imparting durable stain and water resistance to technical textiles, outdoor apparel, and protective fabrics.
• Fluoropolymer Additive: Enhances the processing and surface characteristics of fluoropolymers like PTFE and PVDF, improving dispersion and final product performance.
• Specialty Additive for Electronics: Employed in coatings and cleaning formulations for electronic components where low surface tension and chemical inertness are paramount.
• Fire-Fighting Foam Concentrates (Legacy/Historical): May be used in the formulation of specialized fluorosurfactants for aqueous film-forming foams (AFFF), subject to current global regulatory compliance.
• Release Coatings & Mold Lubricants: Provides excellent non-stick properties in industrial release applications for composites, rubber, and plastics manufacturing.
