Description

3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,12-Heneicosafluoro-1-Dodecanesulfonic Acid Sodium Salt is a high-purity, fully fluorinated anionic surfactant and a key perfluorinated alkyl substance (PFAS). This compound is valued for its exceptional chemical and thermal stability, low surface tension, and unique hydrophobic/oleophobic properties. It is primarily utilized in advanced material science and industrial applications where extreme performance and environmental resistance are critical.

Application

• Fluorinated Surfactant and Leveling Agent: Used in high-performance coatings, paints, and fire-fighting foams (AFFF) to reduce surface tension and improve wetting and film formation.
• Electroplating and Metal Finishing: Acts as a mist suppressant and wetting agent in chromium plating and other hard metal plating baths to improve process efficiency and surface quality.
• Polymerization Aid: Serves as an emulsifier or surfactant in the emulsion polymerization of fluorinated monomers (e.g., PTFE, PVDF) to produce high-performance fluoropolymers.
• Electronic Chemicals: Employed in the formulation of etching solutions and photoresist developers for semiconductor manufacturing due to its purity and stability.
• Analytical Chemistry Standard: Used as a reference standard or an ion-pairing reagent in liquid chromatography-mass spectrometry (LC-MS) for the analysis of various compounds.
• Textile and Leather Treatment: Imparts oil, water, and stain resistance to fabrics, carpets, and leather goods.
