Description

Dimethyl(3,3,4,4,5,5,6,6,6-Nonafluorohexyl)Chlorosilane is a specialized organofluorosilane monomer, a key building block for introducing highly fluorinated alkyl chains onto surfaces and into polymers. This compound matters for its ability to impart exceptional hydrophobicity, oleophobicity, and chemical resistance to materials, significantly altering surface energy and performance. It is primarily needed by manufacturers in the advanced materials, electronics, and specialty coatings industries seeking to create low-surface-energy, non-stick, or self-cleaning properties.

Application

• Surface Modification Agent: Used to create hydrophobic and oleophobic monolayers on glass, silicon, metals, and ceramics for anti-fouling, anti-icing, and easy-clean applications.
• Fluorinated Silicone Synthesis: Serves as a critical monomer for synthesizing high-performance fluorosilicone oils, rubbers, and resins with enhanced solvent and fuel resistance.
• Release Coatings: A key component in formulating high-performance, durable release liners for pressure-sensitive adhesives and molding applications.
• Water & Stain Repellents: Incorporated into treatments for textiles, leather, and paper to provide durable water and oil repellency (DWR).
• Electronic Materials: Used in the passivation and functionalization of semiconductor surfaces and in the development of low-dielectric-constant (low-k) materials.
• Adhesion Promoters: Functions as a coupling agent to improve adhesion between fluorinated polymers and inorganic substrates.
• Specialty Additives: Employed as an additive in lubricants, paints, and coatings to modify surface properties and reduce friction.

Quality Control

Our Dimethyl(3,3,4,4,5,5,6,6,6-Nonafluorohexyl)Chlorosilane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and key impurity profiles are 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). Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong bases and oxidizing agents.
