Description

Sodium 4-[[1,3,4,4,5,5,5-Heptafluoro-2-[2,2,3,3,3-Pentafluoro-1-(Pentafluoroethyl)-1-(Trifluoromethyl)Propyl]-3-(Trifluoromethyl)-1-Pentenyl]Oxy]Benzenesulphonate is a highly fluorinated anionic surfactant with exceptional surface activity and chemical stability. This compound is engineered to deliver superior performance in demanding environments where conventional surfactants fail, offering outstanding thermal and chemical resistance. It is a critical material for advanced manufacturing in the semiconductor, specialty polymer, and high-performance coating industries, where its unique fluorocarbon chain provides unparalleled properties.

Application

• Semiconductor Manufacturing: Used as a surfactant in advanced photoresist formulations and edge bead removal (EBR) solutions for precise wafer patterning.
• Fluoropolymer Processing: Acts as an emulsifier and stabilizer in the polymerization of fluorinated monomers (e.g., PTFE, PFA) and as an additive to enhance dispersion and processing.
• Specialty Coatings & Films: Imparts oil, water, and stain repellency to high-performance coatings, textiles, and membranes due to its low surface energy.
• Fire-Fighting Foams (AFFF): Serves as a key fluorosurfactant component in aqueous film-forming foams for combating flammable liquid fires.
• Electronic Chemicals: Employed in etching and cleaning solutions for electronic components, where its stability in aggressive media is essential.
• Chemical Synthesis Intermediate: Used in the synthesis of more complex fluorinated compounds for pharmaceutical and agrochemical research.
