Description

n-Tetradecyltrichlorosilane is a high-purity organosilicon compound primarily used as a versatile surface modifying agent. Its core value lies in its ability to form durable, hydrophobic, and covalently bonded monolayers on a wide range of inorganic substrates, including glass, silica, and metals. This product is essential for manufacturers and R&D teams in the advanced materials, electronics, and specialty chemical sectors seeking to precisely engineer surface properties for enhanced performance.

Application

• Surface Modification Agent: Used to create hydrophobic, oleophobic, and self-assembled monolayers (SAMs) on glass, silicon wafers, and metal oxides for controlled wettability and adhesion.
• Coupling Agent for Composites: Acts as a silane coupling agent to improve the interfacial adhesion between organic polymers and inorganic fillers (e.g., silica, glass fibers) in composite materials.
• Nanomaterial Functionalization: Employed to functionalize nanoparticles (e.g., silica, titania) and nanotubes to tailor their surface chemistry for dispersion stability and further chemical reactions.
• Chromatography Media: Serves as a derivatization reagent to prepare reversed-phase stationary phases for HPLC and other chromatographic separation techniques.
• Adhesion Promoter: Enhances the bonding of coatings, sealants, and adhesives to difficult-to-bond substrates like glass and metals.
• Corrosion Inhibition: Applied as a precursor for protective coatings on metal surfaces to provide a barrier against moisture and corrosive agents.

Quality Control

Our n-Tetradecyltrichlorosilane is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including Gas Chromatography (GC) and NMR to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flame. Due to its highly volatile and moisture-sensitive nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Recommended storage temperature is 2-8°C for long-term stability.
