Description

n-Ethylheptadecafluoro-n-[3-(trimethoxysilyl)propyl]octanesulphonamide is a high-performance fluorinated organosilane coupling agent that combines the low surface energy of perfluoroalkyl chains with the reactive functionality of a trimethoxysilyl group. This unique structure makes it exceptionally valuable for imparting durable oil, water, and stain repellency to a wide range of inorganic and organic substrates. It is primarily sought after by manufacturers in the advanced materials, coatings, and textile industries seeking to develop high-value, functionalized surfaces with enhanced performance characteristics.

Application

• Surface Modification Agent: Used to create ultra-hydrophobic and oleophobic coatings on glass, ceramics, metals, and polymers for self-cleaning, anti-fouling, and anti-icing applications.
• Textile Finishing: Imparts durable water and oil repellency (DWR/DOR) to technical textiles, outdoor apparel, upholstery, and carpets.
• Paper and Packaging Treatment: Applied to confer grease resistance and moisture barrier properties to specialty papers and food packaging materials.
• Stone and Masonry Protection: Serves as a key component in sealants and treatments to protect building materials from water, oil, and environmental staining.
• Adhesive and Sealant Additive: Enhances the moisture resistance and environmental durability of silicone and other polymer-based formulations.
• Electronics and Optics: Used in the treatment of lenses, displays, and optical components to provide anti-smudge and easy-to-clean surfaces.

Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Key parameters such as purity, identity, and functional group content are verified using advanced analytical techniques including NMR, FT-IR, and HPLC. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory needs.

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 material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent degradation from atmospheric moisture.
