Description

n-Ethylheptadecafluoro-n-[3-(Trichlorosilyl)Propyl]Octanesulphonamide is a high-performance fluorinated silane coupling agent designed to impart exceptional surface properties. This compound is engineered to deliver outstanding oil and water repellency, chemical resistance, and adhesion promotion on inorganic substrates. It is a critical material for manufacturers seeking to create durable, low-surface-energy coatings and composites. Key industries that utilize this advanced chemical include specialty coatings, advanced textiles, and high-performance plastics.

Application

• Surface modification agent for creating superhydrophobic and oleophobic coatings on glass, ceramics, and metals.
• Key intermediate in the synthesis of advanced fluorosurfactants and polymer additives for enhanced performance.
• Coupling agent for improving the adhesion and dispersion of fillers in fluoropolymer composites and elastomers.
• Surface treatment for textiles and nonwovens to achieve durable stain, oil, and water resistance.
• Primer or adhesion promoter in protective and decorative coatings for harsh chemical environments.
• Modifier for silica and other nanoparticles to control surface energy and compatibility in nanocomposites.

Quality Control

Our n-Ethylheptadecafluoro-n-[3-(Trichlorosilyl)Propyl]Octanesulphonamide is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including NMR, FT-IR, and GC-MS to confirm identity and composition. We provide comprehensive Certificates of Analysis (COA) detailing purity, assay, and critical impurity profiles to support your quality assurance protocols and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) in its original packaging to prevent hydrolysis and degradation. Keep away from heat, sparks, and open flame.
