Description

Butanedioic Acid, Sulfo-, 1,4-Bis(Mixed 2,2,3,3,4,4,5,5,6,6,7,7-Dodecafluoroheptyl And 2,2,3,3,4,4,5,5-Octafluoropentyl) Esters, Sodium Salts is a high-performance, fluorinated anionic surfactant and surface modifier. This compound matters for its unique ability to dramatically lower surface tension in demanding environments, offering exceptional chemical and thermal stability due to its perfluorinated alkyl chains. It is critically needed by formulators in industries such as advanced coatings, fire-fighting foams, and specialty chemical processing where standard hydrocarbon surfactants fail.

Application

• As a key fluorosurfactant in aqueous film-forming foams (AFFF) and alcohol-resistant aqueous film-forming foams (AR-AFFF) for superior fire suppression and fuel resistance.
• As a high-performance wetting and leveling agent in advanced industrial and protective coatings, inks, and adhesives.
• As a critical surface tension reducer in electronic chemicals, including photoresists and etching solutions for semiconductor manufacturing.
• As an emulsifier and stabilizer for fluoropolymer dispersions used in non-stick and chemical-resistant coatings.
• In specialty cleaning formulations and surface treatment products requiring stability against harsh chemicals and high temperatures.
• As an additive in oilfield chemicals to enhance flow properties and performance in extreme downhole conditions.
