Description

Diammonium 4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,13-Henicosafluoro-2-Hydroxytridecyl Phosphate is a specialized fluorinated phosphate ester salt, a key building block for advanced surface-active materials. Its unique structure, featuring a long perfluoroalkyl chain, provides exceptional oil and water repellency, low surface energy, and chemical stability. This compound is essential for formulators and manufacturers in industries requiring high-performance, durable surface treatments and specialty surfactants.

Application

• Fluorinated Surfactant Intermediate: A critical precursor for synthesizing high-performance, low-foaming fluorosurfactants used in demanding industrial applications.
• Textile & Fiber Treatment: Imparts durable water, oil, and stain repellency to technical textiles, outdoor apparel, and upholstery fabrics.
• Paper & Packaging Coatings: Used in grease-resistant and moisture-barrier coatings for food packaging and specialty papers.
• Firefighting Foam Concentrates (Legacy Formulations): Historically used as a key component in aqueous film-forming foam (AFFF) for liquid fuel fires. (Note: Subject to global regulatory scrutiny regarding PFAS).
• Specialty Polymer Additive: Enhances surface properties and processing of fluoropolymers and other high-performance plastics.
• Leather & Non-Woven Finishing: Provides soil release and protective finishes for leather goods and technical non-woven materials.
• Electronic Materials: Potential use in coatings for electronic components requiring moisture protection and specific dielectric properties.
