Description

1H,1H,2H,2H-Perfluorodecyltrichlorosilane is a high-purity organosilicon compound featuring a long perfluorinated alkyl chain, making it a premier surface-modifying agent. Its core value lies in its ability to impart exceptional hydrophobicity, oleophobicity, and chemical resistance to substrates like glass, silicon, and metals. This product is essential for manufacturers and R&D teams in the microelectronics, optics, and advanced materials sectors seeking to create low-surface-energy, self-cleaning, or anti-fouling coatings.

Application

• Surface Modification for Microelectronics: Used as a vapor-phase or solution-phase reagent to create hydrophobic monolayers on silicon wafers and other semiconductor surfaces, improving moisture resistance and device reliability.
• Optical & Display Coatings: Applied to glass, lenses, and display screens to provide durable anti-fingerprint, anti-smudge, and easy-to-clean properties.
• Fabric & Textile Treatment: Imparts superior water and oil repellency (stain resistance) to technical textiles and protective clothing.
• MEMS/NEMS Fabrication: Serves as an anti-stiction coating in micro-electromechanical and nano-electromechanical systems to prevent component adhesion.
• Superhydrophobic Surfaces: A key precursor for research and production of superhydrophobic surfaces with high contact angles for applications in fluidics and corrosion protection.
• Adhesion Promotion & Coupling Agent: Functions as a molecular bridge to improve adhesion between inorganic substrates and fluorinated polymers or resins in composite materials.

Quality Control

Our 1H,1H,2H,2H-Perfluorodecyltrichlorosilane is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (GC/HPLC) and spectroscopy (NMR, FTIR), to ensure high chemical purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is 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. Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Recommended storage temperature: 2-8°C for long-term stability.
