Description

(2-Hydroxyethyl)Dimethyl[3-[(3-Sulphopropyl)[(Tridecafluorohexyl)Sulphonyl]Amino]Propyl]Ammonium Hydroxide is a specialized fluorinated zwitterionic surfactant and betaine compound, distinguished by its unique combination of a perfluorinated chain and a quaternary ammonium center. This structure is engineered to deliver exceptional surface activity, thermal stability, and chemical resistance, making it a critical performance additive in demanding formulations. It is primarily sought after by R&D chemists and process engineers in the advanced materials, coatings, and specialty chemical sectors where stability in aggressive environments is paramount.

Application

• Fluorinated Surfactant for Coatings & Inks: Imparts superior leveling, wetting, and anti-cratering properties in high-performance fluoropolymer coatings, paints, and printing inks, especially for applications requiring chemical and stain resistance.
• Firefighting Foam Concentrates (AFFF/FP): Serves as a key fluorosurfactant component in aqueous film-forming foam (AFFF) and film-forming fluoroprotein (FFFP) concentrates for effective hydrocarbon fuel fire suppression.
• Electroplating & Metal Finishing Baths: Enhances wetting and reduces surface tension in acidic or harsh electroplating electrolytes, promoting uniform metal deposition and reducing surface defects.
• Etchant & Cleaning Formulations: Used as a wetting agent in strong acid or solvent-based formulations for precision cleaning, etching, and surface preparation in semiconductor and electronics manufacturing.
• Oil & Gas Production Chemicals: Functions as a corrosion inhibitor and surfactant in acidizing and stimulation fluids for well treatment, where stability under high-temperature, high-pressure, and corrosive conditions is required.
• Specialty Polymer Additive: Incorporated as a processing aid or modifier to improve the surface characteristics and compatibility of engineering plastics and high-performance elastomers.
