1H,1H,2H,2H-Perfluorooctyltriethoxysilane（Cat No.:L019758）is a fluorinated silane coupling agent widely used for surface modification. It features a perfluorinated alkyl chain that imparts exceptional hydrophobicity, oleophobicity, and chemical resistance, along with a triethoxysilane group that reacts with hydroxylated surfaces like glass, metal oxides, and silica. This compound is commonly used to create self-assembled monolayers, anti-fouling coatings, and water-repellent films. Its unique structure makes it ideal for applications in electronics, nanotechnology, and advanced materials where low surface energy and long-term durability are essential for performance and protection.
