Description

Bis((Tridecafluoro-1,1,2,2-Tetrahydrooctyl)Dimethylsiloxy)Methylchlorosilane is a highly fluorinated organosilicon compound, specifically a chlorosilane derivative. This chemical is valued for its ability to impart exceptional hydrophobicity, oleophobicity, and chemical resistance to surfaces and materials. It is primarily used by formulators and manufacturers in advanced material science and specialty coatings industries seeking to create low-surface-energy, non-stick, and protective finishes.

Application

• Surface Modification Agent: Used to create hydrophobic and oleophobic coatings on glass, ceramics, metals, and textiles.
• Release Coatings: A key intermediate for formulating non-stick release layers in industrial molding and packaging applications.
• Water and Stain Repellents: Imparts durable water and oil repellency (DWR) to fabrics, leather, and construction materials.
• Intermediate for Fluorosilicones: Serves as a critical building block in the synthesis of high-performance fluorosilicone polymers and fluids.
• Anti-fouling Coatings: Used in formulations to prevent the adhesion of dirt, ice, or biological organisms on surfaces.
• Electronic Materials: Applied in the surface treatment of electronic components for moisture protection and insulation.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is analyzed to confirm identity, purity, and consistency. Certificates of Analysis (COA) detailing key parameters such as assay (by titration or NMR), chloride content, and impurity profiles are available upon request. We adhere to strict in-process controls to guarantee the reliability required for advanced material synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Recommended storage temperature is 2-8°C for long-term stability.
