Description

n-Ethyl-n-(Heptadecafluorooctyl-So2)Glyc In K Salt,42 Wt% In H2O/2-Butoxyethanol CAS NO 2991-51-7 is a specialized fluorinated surfactant and wetting agent supplied as a 42% aqueous solution in 2-butoxyethanol. This product is engineered to deliver exceptional surface tension reduction and substrate wetting, particularly on low-energy surfaces, due to its unique perfluorooctyl chain. It is a critical performance additive for industries requiring superior leveling, spreading, and anti-foaming properties in challenging formulations. Key users include manufacturers of high-performance coatings, fire-fighting foams, and advanced cleaning products.

Application

• High-Performance Coatings & Paints: As a powerful wetting and leveling agent to improve flow, eliminate craters, and enhance substrate adhesion, especially on plastics and treated metals.
• Fire-Fighting Foams (AFFF - Aqueous Film-Forming Foam): As a key fluorosurfactant component to generate stable, fast-spreading aqueous films that rapidly suppress hydrocarbon fuel fires.
• Industrial & Institutional Cleaners: To boost the wetting and penetrating power of alkaline and acidic formulations used on greasy, oily, or waxy surfaces.
• Textile & Leather Treatment: As a durable water, oil, and stain repellent finish for technical textiles and high-end leather goods.
• Electronic & Precision Cleaning: In formulations for flux removal, degreasing, and cleaning sensitive electronic components where low surface tension and rapid drying are essential.
• Adhesives & Sealants: To improve spreadability and surface contact, ensuring stronger bonds on difficult-to-adhere substrates.

Quality Control

Our production of this fluorosurfactant adheres to strict batch-to-batch consistency protocols. Every lot is analyzed to confirm critical parameters including active content, pH, ionic impurities, and performance in standard surface tension tests. A comprehensive Certificate of Analysis (COA) detailing assay (by titration), identification (IR), and solvent content is provided with each shipment to ensure it meets your formulation specifications and regulatory requirements for intended use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Do not freeze. Keep away from strong acids, strong bases, and strong oxidizing agents. The container should be kept upright to prevent leakage.
