Description

1H,1H,2H,2H-Perfluorodecyldimethylchlorosilane is a high-purity, reactive organosilicon compound featuring a long perfluorinated alkyl chain. This unique structure makes it an exceptionally effective surface modifying agent, imparting durable hydrophobic, oleophobic, and low surface energy properties to a wide range of substrates. It is a critical raw material for manufacturers in the advanced materials, electronics, and specialty coatings sectors seeking to create water- and oil-repellent surfaces with enhanced chemical resistance and release properties.

Application

• Surface Modification Agent: Used to create self-assembled monolayers (SAMs) on silicon, glass, and metal oxides for research and industrial applications.
• Waterproof & Stain-Repellent Coatings: A key ingredient in formulating durable coatings for textiles, leather, paper, and construction materials.
• Mold Release Agents: Provides excellent non-stick properties in polymer processing and composite material manufacturing.
• Microelectronics & Semiconductor Processing: Employed as a vapor-phase primer or adhesion promoter to modify surface energy and improve subsequent layer deposition.
• Nanoparticle Functionalization: Used to cap and stabilize nanoparticles, altering their dispersion properties and compatibility with various matrices.
• Chromatography Stationary Phases: Serves as a derivatization agent to create highly fluorinated, inert surfaces for specialized separation columns.
• Anti-fingerprint Coatings: Formulated into coatings for touchscreens, optical lenses, and display panels.
• Biomedical Device Coatings: Applied to modify surface properties of medical devices to reduce protein adsorption or bacterial adhesion.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is analyzed using advanced techniques including GC, NMR, and FTIR to verify chemical identity, purity, and consistency. Certificates of Analysis (COA) detailing specific batch results are available upon request. We adhere to strict quality management protocols to guarantee the reliability and performance of this specialty silane for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its moisture-sensitive (hygroscopic) nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from heat, sparks, and open flame.
