Description

n-Octylsilane is a versatile organosilicon compound, specifically a linear alkylsilane, that serves as a key building block in surface modification and material science. Its primary value lies in its ability to impart hydrophobic and oleophobic properties to inorganic substrates, enhancing material performance and durability. This product is essential for manufacturers and R&D teams in the coatings, electronics, and advanced materials sectors seeking to functionalize surfaces for improved adhesion, corrosion resistance, or specific chemical interactions.

Application

• Surface Modification Agent: Used as a coupling agent to create hydrophobic monolayers on glass, silica, metals, and other oxide surfaces.
• Silicone Intermediate: Serves as a precursor in the synthesis of specialty silicones, resins, and siloxane polymers with tailored properties.
• Nanomaterial Functionalization: Employed to modify nanoparticles (e.g., silica, titania) to improve dispersion in organic matrices and prevent agglomeration.
• Adhesion Promoter: Enhances the bonding between organic polymers and inorganic fillers or substrates in composite materials.
• Water Repellent Coatings: A key ingredient in formulations for creating water-resistant and stain-resistant coatings on textiles, stone, and construction materials.
• Electronics & Semiconductor: Used in thin-film deposition and as a surface treatment agent in microelectronics fabrication.

Quality Control

Our n-Octylsilane is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR) spectroscopy, to verify identity and assay. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting key specifications 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 place at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Keep away from heat, sparks, and open flame.
