Description

Nonafluorohexyltris(Dimethylsmino)Silane is a highly fluorinated organosilicon compound, specifically a silane coupling agent with a perfluorinated alkyl chain. This structure is critical for imparting exceptional hydrophobicity, oleophobicity, and chemical resistance to treated surfaces. It is primarily utilized as a surface modification agent in advanced materials science and specialty coatings. Industries requiring durable, low-surface-energy materials, such as electronics, optics, and high-performance textiles, rely on this compound for its unique properties.

Application

• Surface Modification Agent: Imparts water and oil repellency (superhydrophobic and oleophobic properties) to glass, ceramics, and metals.
• Electronic Materials: Used as a dielectric layer or surface treatment in semiconductor manufacturing and microelectronics to enhance moisture resistance.
• Optical Coatings: Applied to lenses, displays, and optical sensors to create anti-fingerprint, anti-smudge, and easy-to-clean surfaces.
• Textile Finishing: Provides durable water and stain repellency to technical textiles and outdoor fabrics.
• Adhesion Promotion: Acts as a coupling agent to improve the bonding between fluorinated polymers and inorganic substrates.
• Mold Release Agents: Used in polymer processing to create non-stick surfaces on molds.

Quality Control

Our Nonafluorohexyltris(Dimethylsmino)Silane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by NMR or GC, purity verification, and confirmation of critical physical properties. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to ensure compliance with your specifications and industry standards.

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 (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
