Description

(4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,11-Heptadecafluoro-2-Hydroxyundecyl)Bis(2-Hydroxyethyl)Methylammonium Iodide is a highly fluorinated quaternary ammonium salt, a specialized class of surfactant known for its exceptional surface activity and chemical stability. This compound matters for its unique combination of hydrophobicity from the long perfluorinated chain and the hydrophilic, cationic character of the ammonium head group, enabling it to lower surface tension in demanding environments. It is primarily needed by R&D chemists and formulators in the advanced materials, electronics, and specialty chemical sectors for applications requiring fluorosurfactants, such as coatings, fire-fighting foams, and as a potential intermediate for further chemical synthesis.

Application

• Fluorosurfactant in High-Performance Coatings: Imparts exceptional wetting, leveling, and anti-cratering properties in solvent-based and fluoropolymer coatings for industrial and architectural applications.
• Additive for Fire-Fighting Foams (AFFF): Serves as a key fluorosurfactant component in aqueous film-forming foams, enhancing fuel sealant properties and foam stability for Class B fires.
• Surface Modifier for Electronics: Used to treat surfaces to impart oil, water, and stain repellency in the manufacturing of electronic components and displays.
• Intermediate for Specialty Chemicals: Acts as a versatile building block for synthesizing more complex fluorinated quaternary ammonium compounds with tailored properties.
• Research & Development: Employed in academic and industrial labs for studying the behavior of fluorinated surfactants, self-assembly, and novel material properties.
