Description

Ammonium Bis[3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,14,15,15,16,16,16-Nonacosafluorohexadecyl] Phosphate is a high-performance fluorinated ammonium salt surfactant. This compound is engineered to deliver exceptional surface tension reduction and outstanding chemical and thermal stability in demanding environments. It is a critical raw material for industries requiring durable water and oil repellency, low surface energy coatings, and superior release properties. Its unique perfluorinated alkyl chains provide the ultimate in performance for advanced material science applications.

Application

• Fluorinated Surfactant & Leveling Agent: Used in high-performance coatings, paints, and inks to improve wetting, leveling, and reduce surface defects on difficult substrates.
• Water & Oil Repellent Finishes: A key ingredient for treating textiles, leather, paper, and non-woven fabrics to impart durable stain and liquid repellency.
• Release Coatings: Formulated into mold release agents for plastics, rubber, and composite manufacturing, providing excellent non-stick properties.
• Fire-Fighting Foams (Legacy/Historical): Historically used in certain classes of aqueous film-forming foams (AFFF) for liquid fuel fires, though regulations are evolving.
• Specialty Additive for Polymers: Incorporated into fluoropolymers and other high-performance plastics to enhance surface characteristics and processing.
• Electronics & Semiconductor Industry: Used in photoresist formulations and as an anti-static or surface-modifying agent in precision cleaning solutions.

Quality Control

Our production of this fluorosurfactant adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as purity, active content, and ionic impurities are monitored using advanced analytical techniques including HPLC, NMR, and titration. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and specific properties is provided with each shipment. We are committed to supplying material that meets the stringent requirements of industrial and specialty chemical applications.

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); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance. Keep away from strong oxidizing agents and strong bases.
