Description

n-Ethyl-1,1,2,2,3,3,4,4,5,5,6,6,7,7,7-pentadecafluoro-n-[3-(trichlorosilyl)propyl]heptane-1-sulphonamide is a highly specialized fluorinated silane coupling agent designed for demanding surface modification applications. This compound is engineered to provide exceptional chemical resistance and low surface energy by combining a long perfluoroalkyl chain with a reactive trichlorosilyl anchor group. It is primarily utilized by manufacturers in the advanced materials, electronics, and specialty coatings sectors seeking to impart permanent hydrophobic, oleophobic, and release properties to substrates like glass, metals, and ceramics.

Application

• Surface modification agent for creating ultra-durable, low-energy coatings on glass, metals, and ceramics.
• Key intermediate in the synthesis of advanced fluorinated polymers and silicones for high-performance materials.
• Primer or adhesion promoter in specialty paints and coatings requiring chemical resistance and water repellency.
• Surface treatment for optical fibers and electronic components to enhance environmental stability.
• Manufacture of release liners and anti-stick surfaces in industrial molding processes.
• Modification of fillers and nanoparticles to improve dispersion and compatibility in fluoropolymer matrices.
• Research and development of novel self-assembled monolayers (SAMs) for sensor and microfluidic device fabrication.

Quality Control

Our production of n-Ethyl-1,1,2,2,3,3,4,4,5,5,6,6,7,7,7-pentadecafluoro-n-[3-(trichlorosilyl)propyl]heptane-1-sulphonamide adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing, including NMR, FT-IR, and HPLC, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and key physical parameters are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored under a dry, inert atmosphere (e.g., nitrogen or argon) in a cool, dry place. Recommended storage temperature is 2-8°C to maximize shelf life and maintain reactivity. Ensure the storage area is well-ventilated and separate from incompatible materials such as strong bases and oxidizers.
