Description

Ammonium Bis[3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,12,12,12-Icosafluoro-11-(Trifluoromethyl)Dodecyl] Phosphate is a high-performance fluorinated ammonium salt surfactant. This compound is engineered to deliver exceptional surface activity, thermal stability, and chemical resistance due to its unique perfluorinated alkyl chain structure. It is a critical material for industries requiring advanced surface modification, where standard hydrocarbon-based surfactants fail. The CAS number for this compound is 93776-25-1.

Application

• Firefighting Foams (AFFF): A key fluorosurfactant component in aqueous film-forming foams for rapidly suppressing hydrocarbon fuel fires.
• Specialty Coatings and Inks: Provides superior leveling, wetting, and anti-cratering properties in high-performance fluoropolymer coatings and printing inks.
• Oil & Gas Industry: Used in drilling fluids and oil recovery formulations as a high-temperature stable surfactant and wetting agent.
• Electronics Manufacturing: Employed as a surfactant in etching baths and cleaning solutions for semiconductor wafers and electronic components.
• Textile and Leather Treatment: Imparts durable oil, water, and stain repellency to fabrics and leather goods.
• Advanced Polymer Processing: Acts as an emulsifier and processing aid in the synthesis and molding of fluoroplastics like PTFE.
