Description

Nonafluorohexyltriethoxysilane is a high-purity organofluorine silane coupling agent, a critical intermediate for imparting exceptional surface properties. Its core value lies in its ability to create durable, low-energy surfaces with outstanding oil, water, and chemical repellency. This compound is essential for manufacturers in the coatings, textiles, electronics, and advanced materials sectors seeking to enhance product performance and longevity.

Application

• Surface Modification Agent: Used to create hydrophobic and oleophobic coatings on glass, ceramics, and metals for anti-fouling, anti-stain, and easy-clean applications.
• Textile Finishing: Imparts durable water and oil repellency (DWR/DOR) to technical fabrics, outdoor gear, and protective clothing.
• Electronic Encapsulation: Serves as a key ingredient in formulations for protecting electronic components from moisture and environmental contaminants.
• Adhesive & Sealant Additive: Enhances the adhesion and moisture resistance of silicone-based adhesives and sealants, particularly on difficult-to-bond substrates.
• Stone & Masonry Protection: Formulated into treatments that provide long-lasting water repellency and stain resistance to natural stone, concrete, and brick.
• Optical Films & Displays: Used in anti-reflective and anti-smudge coatings for lenses, displays, and optical components.

Quality Control

Our Nonafluorohexyltriethoxysilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and key physical properties 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). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent degradation from atmospheric moisture.
