Description

Diammonium 4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,15,15,15-Tetracosafluoro-2-Hydroxy-14-(Trifluoromethyl)Pentadecyl Phosphate is a highly fluorinated phosphate ester salt, engineered to deliver exceptional surface activity and chemical stability. This compound is valued for its ability to impart oil, water, and stain repellency, as well as to lower surface tension in demanding formulations. It is a critical raw material for manufacturers in the specialty coatings, performance textiles, and advanced fluorosurfactant industries seeking durable, high-performance properties.

Application

• Fluorosurfactant Precursor: A key intermediate for synthesizing high-performance, low-surface-tension fluorosurfactants used in firefighting foams, coatings, and electronics.
• Textile Finishing Agent: Imparts durable water, oil, and stain repellency to technical fabrics, outdoor apparel, and upholstery.
• Specialty Coating Additive: Enhances the surface properties of industrial, architectural, and anti-graffiti coatings for improved weatherability and cleanability.
• Paper and Packaging Treatment: Used to create grease-resistant and moisture-barrier coatings for food packaging and specialty papers.
• Polymer Modification: Incorporated as a comonomer or additive to introduce fluorinated segments into polymers, improving chemical resistance and surface characteristics.
• Electronics Industry: Potential use in formulations for electronic coatings where moisture protection and low dielectric properties are critical.
