Description

Trimethylsilyl Perfluorononanoate is a specialized organofluorine compound featuring a perfluorinated alkyl chain and a trimethylsilyl ester group. This unique molecular architecture provides exceptional hydrophobicity, oleophobicity, and chemical stability, making it a high-performance intermediate for advanced surface modification. It is critically needed by R&D chemists and formulators in the specialty chemical and advanced materials sectors seeking to impart permanent, low-surface-energy properties. Key applications include the synthesis of sophisticated fluorosurfactants, water- and oil-repellent coatings, and release agents.

Application

• Fluorosurfactant & Polymer Intermediate: Serves as a key building block for synthesizing high-performance, low-foam fluorosurfactants and fluorinated polymers.
• Surface Modification Agent: Imparts durable water, oil, and stain repellency to textiles, leather, paper, and non-woven fabrics.
• Release Coatings: Used in formulations for mold release agents in plastics, rubber, and composite manufacturing.
• Specialty Additives: Functions as a leveling or wetting agent in high-performance coatings, inks, and adhesives.
• Electronics & Optics: Potential application in anti-fingerprint coatings for displays and optical components.
• Laboratory Reagent: Employed in organic synthesis as a derivatization agent or to introduce fluorinated chains.

Quality Control

Our Trimethylsilyl Perfluorononanoate is manufactured under strict quality management protocols. Every batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical specifications. Our quality commitment ensures the material meets the high standards required for research and industrial applications.

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