Description

Hexyltrifluorosilane is a high-purity organosilicon compound, specifically a fluorinated alkylsilane, with the CAS number 96164-66-8. It serves as a critical surface modification agent, valued for its ability to impart hydrophobic and oleophobic properties to a wide range of substrates. This chemical is essential for manufacturers and R&D facilities in the advanced materials, electronics, and specialty coatings sectors seeking to engineer surfaces with specific functional characteristics.

Application

• Surface Modification Agent: Used to create hydrophobic and oleophobic self-assembled monolayers (SAMs) on glass, silicon, and metal oxides.
• Electronics Manufacturing: Applied as a dielectric layer precursor or adhesion promoter in semiconductor fabrication and micro-electromechanical systems (MEMS).
• Nanotechnology: Functionalizes nanoparticles (e.g., silica, metal oxides) to control dispersion and surface reactivity in composite materials.
• Specialty Coatings: A key ingredient in formulating water-repellent, anti-fingerprint, and anti-corrosion coatings for optical lenses, displays, and precision instruments.
• Chemical Synthesis: Acts as an intermediate or protecting group reagent in the synthesis of more complex organosilicon molecules and pharmaceuticals.
• Adhesive & Sealant Industry: Enhances the adhesion and moisture resistance of silicone-based formulations.

Quality Control

Our Hexyltrifluorosilane is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support traceability and documentation requirements for global supply chains, including REACH and other relevant regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
