Description

n-Ethyl-1,1,2,2,3,3,4,4,5,5,6,6,7,7,7-pentadecafluoro-n-[3-(trimethoxysilyl)propyl]heptane-1-sulphonamide is a high-performance fluorinated organosilane coupling agent, uniquely combining a long perfluoroalkyl chain with a reactive silane head group. This molecular structure provides exceptional surface energy reduction and durable hydrophobicity/oleophobicity when grafted onto substrates. It is a critical raw material for manufacturers requiring advanced surface modification, offering superior chemical and thermal stability compared to non-fluorinated alternatives. Key industries that utilize this specialty chemical include advanced coatings, electronics, textiles, and high-performance composites.

Application

• Surface Modification Agent: Imparts permanent water, oil, and stain repellency to textiles, leather, and non-woven fabrics.
• Advanced Coatings Formulation: Used as a key additive in anti-graffiti, anti-fingerprint, and easy-clean coatings for glass, metals, and ceramics.
• Electronic Materials: Enhances moisture resistance and dielectric properties in electronic encapsulants, circuit boards, and optical fiber coatings.
• Composite Materials: Acts as a coupling agent to improve adhesion between fluorinated polymers or fillers and various matrices.
• Stone and Masonry Protection: Provides deep-seated, breathable water repellency for architectural preservation.
• Mold Release Agents: Serves as a high-performance component in release coatings for industrial molding processes.
• Paper and Packaging Treatment: Used to create grease and moisture-resistant barriers for specialty papers and food packaging.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated place at room temperature (15-25°C/59-77°F). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation. Keep away from heat and incompatible materials.
