Description

Sodium 1-(2,2,3,3,4,4,5,5,6,6,7,7-Dodecafluoroheptyl) 2-Sulphonatobenzoate is a specialized fluorinated surfactant and anionic compound that combines a highly fluorinated alkyl chain with a sulfonated aromatic head group. This unique structure provides exceptional surface activity, chemical stability, and oil/water repellency, making it a critical performance additive in demanding formulations. It is primarily utilized in industries requiring advanced materials with low surface energy and high resistance to harsh environments, such as high-performance coatings, firefighting foams, and specialty chemical synthesis.

Application

• Aqueous Film-Forming Foam (AFFF) Concentrates: A key fluorosurfactant component for generating fast-spreading, fuel-resistant firefighting foams used in Class B hydrocarbon fires.
• High-Performance Coatings and Paints: Acts as a leveling and wetting agent in fluoropolymer and industrial coatings, enhancing substrate coverage and providing stain, oil, and water repellency.
• Textile and Leather Treatment: Imparts durable water and oil repellent (DWR) finishes to fabrics, carpets, and leather goods.
• Specialty Cleaning and Polishing Formulations: Used in products requiring superior wetting and soil release properties on low-energy surfaces like plastics and treated metals.
• Chemical Synthesis Intermediate: Serves as a building block for synthesizing more complex fluorinated compounds in pharmaceutical and agrochemical research.
• Paper and Packaging Coatings: Provides grease and moisture resistance for food packaging and specialty paper products.

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 performance. Keep away from strong oxidizing agents.
