Description

1H,1H,2H,2H-Perfluorotetradecyltrichlorosilane is a high-purity, long-chain perfluorinated organosilane coupling agent. This compound is engineered to impart exceptional hydrophobicity, oleophobicity, and chemical resistance to surfaces through covalent bonding. It is a critical material for manufacturers in advanced materials science, nanotechnology, and high-performance coatings who require durable, low-surface-energy modifications. The product is supplied under strict quality control to ensure batch-to-batch consistency for demanding industrial and research applications.

Application

• Surface Modification Agent: Used to create superhydrophobic and oleophobic coatings on glass, silicon, metals, and ceramics for self-cleaning, anti-fouling, and anti-icing properties.
• Nanotechnology & Microfabrication: Serves as a monolayer-forming material in MEMS (Micro-Electro-Mechanical Systems) and NEMS (Nano-Electro-Mechanical Systems) to reduce stiction and friction.
• Textile & Fiber Treatment: Imparts durable water and oil repellency (DWR) to technical textiles, outdoor apparel, and filtration media.
• Paper & Packaging Coatings: Applied to create grease-resistant and moisture-barrier coatings for specialty papers and food packaging.
• Electronic Component Protection: Used to form protective, moisture-resistant layers on sensitive electronic components and printed circuit boards (PCBs).
• Biomedical Device Coatings: Enhances the biocompatibility and reduces protein adsorption on medical implants and diagnostic devices.
• Stone & Concrete Sealants: Provides deep penetration and long-lasting water repellency for architectural preservation and construction materials.
• Research & Development: A key reagent in academic and industrial R&D for studying surface chemistry, thin films, and advanced composite materials.

Quality Control

Our 1H,1H,2H,2H-Perfluorotetradecyltrichlorosilane is manufactured under controlled conditions and undergoes rigorous analytical testing to ensure high purity and performance consistency. Each batch is validated against stringent in-house specifications, with key parameters including purity (assay), identity, and moisture content. A Certificate of Analysis (COA) detailing these results 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, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and reactive with strong bases; containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation. Keep away from heat, sparks, and open flame.
