Description

1-[2-(2-Butoxyethoxy)Ethoxy]-4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,11-Heptadecafluoroundecan-2-Ol is a high-performance fluorinated surfactant and intermediate characterized by its unique hybrid structure combining a polyfluorinated alkyl chain with an ethoxylated segment. This compound matters for its exceptional ability to dramatically lower surface tension in both aqueous and organic systems, providing superior wetting, leveling, and anti-foaming properties. It is primarily needed by formulators in the coatings, electronics, and specialty chemical industries seeking to enhance product performance with advanced fluorochemical technology.

Application

• Fluorinated Surfactant for Coatings & Inks: Imparts exceptional wetting, leveling, and anti-cratering properties in high-performance fluoropolymer coatings, paints, and printing inks.
• Electronic Chemicals: Used as a wetting and leveling agent in photoresist formulations and as an additive in electronic coating fluids for semiconductor manufacturing.
• Firefighting Foams (AFFF): Serves as a key fluorosurfactant component in aqueous film-forming foams (AFFF) for combating flammable liquid fires.
• Oil & Gas Field Chemicals: Acts as a flow improver and surfactant in drilling fluids, fracturing fluids, and crude oil recovery processes.
• Textile & Leather Treatment: Provides durable water, oil, and stain repellency when used as a finishing agent for fabrics and leather goods.
• Specialty Cleaning Formulations: Enhances the cleaning efficacy and surface wetting in industrial and institutional cleaners for difficult soils.
• Polymer Additive: Functions as a processing aid and surface modifier in the manufacture of fluoropolymers and other high-performance plastics.
• Chemical Intermediate: Utilized in the synthesis of more complex fluorinated compounds for pharmaceutical and agrochemical research.
