Description

Bis(Nonafluorohexyl)Dichlorosilane is a high-purity organofluorosilane compound, serving as a critical intermediate for introducing highly fluorinated alkyl chains onto surfaces and into polymer matrices. Its value lies in providing exceptional hydrophobicity, oleophobicity, and chemical resistance to materials, making it indispensable for advanced surface engineering. This product is primarily needed by manufacturers in the electronics, specialty coatings, and high-performance materials sectors seeking to create low-surface-energy, durable finishes.

Application

• Surface Modification Agent: Key precursor for creating self-assembled monolayers (SAMs) on silicon, glass, and metal oxides to impart water- and oil-repellent properties.
• Fluorinated Silicone Synthesis: Essential monomer for synthesizing specialty fluorosilicone polymers and elastomers with enhanced solvent and fuel resistance.
• Electronic Materials: Used in the formulation of low-dielectric-constant (low-k) materials and protective coatings for microelectronic components.
• Textile & Leather Treatment: Imparts durable stain and water resistance to fibers, fabrics, and leather goods.
• Optical & Anti-Reflective Coatings: Contributes to the formulation of coatings for lenses and displays where environmental protection is required.
• Adhesive & Sealant Modifier: Enhances the surface wetting and release properties of industrial adhesives and sealants.

Quality Control

Our Bis(Nonafluorohexyl)Dichlorosilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Keep away from moisture, strong bases, and oxidizing agents.
