Description

Bis(2-Hydroxyethyl)Ammonium 1,1,2,2,3,3,4,4,5,5,5-Undecafluoropentane-1-Sulphonate is a specialized fluorinated surfactant salt that combines the unique properties of a perfluorinated alkyl chain with a hydrophilic ammonium sulphonate head group. This compound is valued for its exceptional surface activity, thermal stability, and chemical inertness, making it a critical performance additive in demanding industrial formulations. It is primarily sought after by manufacturers in the electronics, coatings, and fire-fighting foam industries where superior wetting, leveling, and stability are required.

Application

• Electronics Manufacturing: As a surfactant in photoresist strippers and cleaning solutions for semiconductor wafers and printed circuit boards (PCBs), providing excellent wetting and residue removal.
• Fluorinated Fire-Fighting Foams (AFFF/AR-AFFF): A key ingredient in formulating high-performance, film-forming fluoroprotein foams for combating hydrocarbon fuel fires.
• Specialty Coatings & Inks: Used to improve flow, leveling, and substrate wetting in high-performance fluoropolymer coatings and inks, reducing surface defects.
• Metal Plating & Surface Treatment: Acts as a wetting agent and mist suppressant in chromium plating and other metal finishing baths to enhance surface quality and process safety.
• Polymerization Aid: Serves as an emulsifier or surfactant in the emulsion polymerization of fluorinated monomers for producing PTFE, FKM, and other fluoropolymers.
• Oil & Gas Industry: Utilized in formulations for acidizing and fracturing fluids where chemical and thermal stability under harsh downhole conditions is critical.

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 after opening to prevent absorption of atmospheric moisture, which can affect product performance.
