Description

Diammonium 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,14,15,16,16,16-Octacosafluoro-15-(Trifluoromethyl)Hexadecyl Phosphate is a highly fluorinated phosphate ester salt, engineered to deliver exceptional surface activity and chemical stability. This compound matters for its unique ability to impart outstanding oil, water, and stain repellency, as well as low surface energy, to a wide range of materials. It is primarily needed by formulators in the advanced coatings, specialty surfactant, and fluoropolymer modification industries seeking to enhance performance characteristics.

Application

• As a key fluorosurfactant and leveling agent in high-performance, water- and oil-repellent coatings and paints.
• As an additive for imparting stain resistance and soil release properties to textiles and technical fabrics.
• In the formulation of fire-fighting foams (AFFF) requiring superior film-forming and spreading capabilities.
• As a surface modifier and processing aid in the manufacture of fluoropolymers and specialty plastics.
• For creating anti-fogging and anti-reflective coatings on optical lenses and displays.
• In the development of release coatings for molds and non-stick applications.
• As an emulsifier and stabilizer in fluorinated specialty chemicals and emulsion systems.
• For research and development of novel materials requiring extreme hydrophobicity and oleophobicity.

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); ensure containers are sealed immediately after use to prevent degradation from atmospheric moisture. Keep away from strong acids, bases, and oxidizing agents.
