Description

Bis(Nonafluorohexyldimethylsiloxy)Methylsilane,95% CAS NO 147986-73-0 is a high-purity, fluorinated organosilicon compound. This specialty chemical is valued for its ability to impart exceptional hydrophobicity, oleophobicity, and chemical resistance to surfaces. It is primarily needed by manufacturers in the coatings, textiles, and electronics industries for creating advanced protective and functional layers.

Application

• Surface Modification Agent: Used to create ultra-durable water- and oil-repellent (omniphobic) coatings on glass, ceramics, and metals.
• Textile Finishing: Imparts permanent stain and water resistance to technical fabrics, outdoor gear, and upholstery.
• Electronic Encapsulants: Serves as a key ingredient in protective coatings for printed circuit boards (PCBs) and sensitive electronic components to prevent moisture ingress and corrosion.
• Mold Release Agents: Provides excellent non-stick properties in high-performance polymer processing and composite molding.
• Additive for Polymers & Elastomers: Enhances the surface properties and environmental stability of silicones and fluoropolymers.
• Anti-fouling Coatings: Used in marine and industrial applications to prevent the adhesion of biological organisms and contaminants.

Quality Control

Our Bis(Nonafluorohexyldimethylsiloxy)Methylsilane is produced under strict quality management protocols. Every batch undergoes rigorous analytical testing, including GC, NMR, and FTIR analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting the assay and key impurity profiles are available upon request to support your quality assurance and regulatory needs.

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). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation from atmospheric moisture.
