Description

Diammonium 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,14,14-Pentacosafluorotetradecyl Phosphate is a specialized fluorinated phosphate ester salt, designed to impart exceptional oil, water, and stain repellency to surfaces. Its unique perfluorinated alkyl chain provides superior surface energy reduction, making it a critical performance additive in advanced material formulations. This compound is essential for manufacturers in the textile, coatings, and specialty polymer industries seeking to develop high-performance, durable, and easy-to-clean products.

Application

• Textile Finishing Agent: As a key component in durable water repellent (DWR) and stain release finishes for outdoor apparel, upholstery, and technical fabrics.
• Paper and Packaging Coatings: To create grease-resistant and moisture-barrier coatings for food packaging, cardboard, and specialty papers.
• Industrial and Protective Coatings: Incorporated into paints and coatings for buildings, automotive, and marine applications to enhance dirt pickup resistance and ease of cleaning.
• Leather Treatment: Used to provide stain and water resistance to finished leather goods, including footwear, bags, and furniture.
• Firefighting Foam Formulations (Legacy Systems): Historically used in certain aqueous film-forming foam (AFFF) concentrates for liquid fuel fires (subject to regional regulations on PFAS).
• Specialty Polymer Additive: As a surface-modifying additive in plastics and fibers to improve anti-soiling and release properties.

Quality Control

Our production of Diammonium 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,14,14-Pentacosafluorotetradecyl Phosphate adheres to a strict quality management system. Every batch is analyzed to ensure consistent composition, purity, and performance. Key parameters such as assay, fluoride content, and pH are rigorously tested. A comprehensive Certificate of Analysis (COA) documenting these results is provided with each shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance and stability. Keep away from strong acids and strong bases.
