Description

Ammonium Bis[3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,12-Henicosafluorododecyl] Phosphate CAS NO 93776-21-7 is a high-performance, fluorinated anionic surfactant and surface modifier. This compound is engineered to deliver exceptional surface tension reduction and outstanding chemical and thermal stability due to its long perfluoroalkyl chains. It is a critical material for industries requiring durable, low-energy surfaces and enhanced performance in demanding environments. Key applications include advanced coatings, fire-fighting foams, and specialty chemical formulations where superior water and oil repellency is paramount.

Application

• As a key surfactant and foam stabilizer in aqueous film-forming foam (AFFF) and fluoroprotein fire-fighting formulations.
• As a durable surface treatment agent to impart oil, water, and stain repellency to textiles, carpets, and paper products.
• As an additive in coatings, paints, and inks to improve leveling, wetting, and substrate adhesion while providing release properties.
• As a critical component in polishing slurries and electronic chemicals for the semiconductor manufacturing process.
• As a surfactant and emulsifier in specialty polymerizations and high-performance fluoropolymer dispersions.
• For creating low-surface-energy coatings for medical devices and anti-fouling marine applications.
• As an additive in lubricants and greases to enhance performance under extreme pressure and temperature conditions.
