Description

2-(Sodiosulfo)Succinic Acid Bis(2,2,3,3-Tetrafluoropropyl) Ester is a specialized fluorinated anionic surfactant and functional monomer, valued for its unique combination of oil and water repellency, chemical resistance, and surface activity. Its core value proposition lies in imparting durable, low-surface-energy properties to materials, making them resistant to water, oils, and harsh chemicals. This compound is essential for manufacturers in the coatings, textile finishing, and advanced polymer industries seeking to develop high-performance, fluorinated products.

Application

• Fluorinated Polymer Synthesis: Acts as a key monomer for producing fluorinated polyurethanes, acrylics, and epoxy resins with enhanced chemical and stain resistance.
• High-Performance Coatings & Paints: Used as an additive to create hydrophobic and oleophobic surface coatings for automotive, aerospace, and architectural applications.
• Textile & Fiber Treatment: Imparts durable water and oil repellency (DWR/DOR) to technical textiles, outdoor apparel, and upholstery fabrics.
• Fire-Fighting Foams (AFFF): Serves as a fluorosurfactant component in aqueous film-forming foams for combating flammable liquid fires.
• Specialty Surfactants & Leveling Agents: Provides superior wetting and leveling in formulations for electronics, coatings, and cleaning products where fluorinated chemistry is required.
• Paper & Packaging Coatings: Used to create grease-resistant and moisture-barrier coatings for food packaging and specialty papers.
