Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-2-Ethyl(Pentadecafluoroheptyl)Sulfonylaminoethyl-.Omega.-Hydroxy- is a high-performance fluorinated polyether derivative, distinguished by its unique perfluoroalkyl sulfonamide segment. This compound is engineered to deliver exceptional surface activity, chemical inertness, and thermal stability, making it a critical additive in demanding industrial formulations. It is primarily sought after by manufacturers in the coatings, specialty polymer, and advanced material sectors where low surface energy, oil/water repellency, and compatibility with fluorinated systems are paramount. The CAS number for this substance is 68298-81-7.

Application

• Fluorinated Surfactant & Leveling Agent: A key ingredient in high-performance coatings, paints, and inks to reduce surface tension, improve wetting, and prevent defects like craters and orange peel.
• Oil & Water Repellent Treatments: Used to impart durable stain, oil, and water resistance to textiles, leather, paper, and non-woven fabrics.
• Additive for Fluoropolymer Processing: Enhances the processing and surface properties of PTFE, FEP, and PFA, acting as a lubricant and dispersion aid.
• Fire-Fighting Foam Concentrates (AFFF/AR-AFFF): Serves as a critical fluorosurfactant component in aqueous film-forming foams for rapid fire suppression of flammable liquid fires.
• Mold Release Agents: Provides excellent non-stick properties in plastic, rubber, and composite molding applications.
• Electronic & Semiconductor Coatings: Used in protective conformal coatings and anti-fingerprint treatments due to its chemical resistance and dielectric properties.
