Description

Poly(Difluoromethylene), α-[2-(Acetyloxy)-2- [(Carboxymethyl)Dimethylammonio]Ethyl]-ω-Fluoro -, Hydroxide, Inner Salt CAS NO 71002-41-0 is a specialized fluorinated surfactant and zwitterionic compound. Its unique molecular structure, featuring both fluorocarbon chains and a betaine moiety, provides exceptional surface activity, chemical stability, and compatibility in demanding formulations. This high-performance chemical is essential for manufacturers requiring advanced wetting, leveling, and anti-foaming properties in complex systems.

Application

• Firefighting Foams (AFFF): A key fluorosurfactant component in aqueous film-forming foams for rapid knockdown of hydrocarbon fuel fires.
• Specialty Coatings & Inks: Provides superior wetting, leveling, and anti-cratering properties in high-solids, UV-curable, and water-based coating systems.
• Electronics Cleaning Fluids: Used as a surfactant in precision cleaning formulations for semiconductors and electronic components due to low surface tension and high stability.
• Oil & Gas Field Chemicals: Functions as a flow improver and surfactant in drilling muds, fracturing fluids, and anti-foaming agents.
• Polymerization Aid: Acts as an emulsifier and stabilizer in the emulsion polymerization of fluoropolymers and other high-performance plastics.
• Personal Care & Cosmetic Formulations: Employed in specialized cosmetic products for its unique spreading characteristics and skin compatibility (subject to grade and regulatory approval).
