Description

Bis(2,2,3,3,4,4,5,5,6,6,7,7-Dodecafluoroheptyl) Sulfosuccinate Sodium Salt is a high-performance, fluorinated anionic surfactant renowned for its exceptional surface activity and chemical stability. Its unique perfluoroalkyl chain structure provides superior oil and water repellency, low surface tension, and excellent thermal and chemical resistance. This makes it a critical material for demanding industrial applications where standard hydrocarbon surfactants fail, particularly in advanced coatings, fire-fighting foams, and specialty chemical formulations.

Application

• As a key fluorosurfactant in aqueous film-forming foams (AFFF) and fire-fighting concentrates for superior fuel resistance and film formation.
• Critical component in oil and water repellent treatments for textiles, leather, and paper products.
• Leveling and wetting agent in high-performance fluoropolymer coatings, paints, and inks to enhance surface coverage and finish.
• Emulsifier and stabilizer for the synthesis and processing of fluorinated monomers and polymers.
• Additive in electronic chemicals and cleaning formulations for precision surface treatment.
• Used in specialty detergent formulations requiring stability in harsh chemical environments.
• Potential applications in imaging and photographic materials as a coating aid.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance. Keep away from incompatible materials such as strong oxidizing agents.
