Description

2-[Ethyl[(1,1,2,2,3,3,4,4,5,5,5-Undecafluoropentyl)Sulphonyl]Amino]Ethyl Dihydrogen Phosphate is a specialized fluorinated anionic surfactant and phosphate ester, distinguished by its unique perfluorinated alkyl chain. This compound is engineered to deliver exceptional surface activity, chemical resistance, and thermal stability, making it a critical performance additive in demanding industrial formulations. It is primarily sought after by manufacturers in the fire-fighting foam, specialty coatings, and advanced polymer sectors where its fluorinated structure imparts superior oil and water repellency.

Application

• Aqueous Film-Forming Foam (AFFF) Concentrates: A key fluorosurfactant component for creating fast-spreading, fuel-resistant fire-fighting foams.
• Stain & Oil-Repellent Coatings: Used in textile finishing and protective surface treatments for paper, leather, and carpets.
• Fluoropolymer Processing Aids: Acts as a surfactant and leveling agent in the production of PTFE, PVDF, and other high-performance fluoropolymers.
• Specialty Detergents & Cleaners: Provides superior wetting and soil release properties in industrial and institutional cleaning formulations.
• Electronic Chemicals: Utilized as a wetting agent in photoresist developers and etching solutions for semiconductor manufacturing.
• Metal Plating & Surface Treatment: Enhances wetting and leveling in electroplating baths and conversion coatings.

Quality Control

Every batch of our fluorinated phosphate ester is produced under a strict quality management system. We employ advanced analytical techniques including HPLC, NMR, and titration to verify identity, purity, and functional group content. A comprehensive Certificate of Analysis (COA) detailing assay, moisture content, and impurity profile is provided with each shipment to ensure it meets your precise formulation requirements.

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 degradation. Keep away from strong acids and strong oxidizing agents.
