Description

1,1-Dichloro-3,3,3-trimethyl-1-(3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl)disiloxane is a highly specialized organofluorosilane compound that combines a reactive chlorosilane head with a long, hydrophobic perfluoroalkyl tail. This unique structure makes it an invaluable intermediate for introducing fluorinated, hydrophobic, and oleophobic properties onto silicon-based materials. It is primarily sought by R&D and production teams in advanced materials science, particularly for creating high-performance surface modifiers, release agents, and protective coatings. The compound, identified by CAS number 94237-17-9, is critical for applications demanding extreme chemical resistance and low surface energy.

Application

• Surface Modification Agent: Imparts durable water, oil, and stain repellency to textiles, paper, and non-woven fabrics.
• Release Coating Intermediate: Used in the synthesis of silicone release liners for pressure-sensitive adhesives and industrial molding processes.
• Protective Coatings: Serves as a key building block for formulating advanced protective coatings on glass, metals, and ceramics to enhance corrosion and chemical resistance.
• Fluorinated Silicone Synthesis: An essential monomer for producing specialty fluorosilicone polymers with enhanced solvent resistance and thermal stability.
• Microelectronics & Optics: Used in the fabrication of anti-reflective, anti-fogging, or self-cleaning coatings for optical components and electronic devices.
• Additive for Polymers & Elastomers: Incorporated into formulations to improve the surface properties, lubricity, and environmental resistance of plastics and rubbers.

We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing key specifications such as assay, identity, and impurity profiles. Our quality commitment supports applications requiring reliable performance and traceability in advanced material synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize hydrolysis and volatility. Due to its moisture-sensitive and highly volatile nature, containers must be kept sealed under an inert atmosphere (argon or nitrogen) when not in use. Keep away from strong acids and organic solvents.
