Description

1H,1H,2H,2H-Perfluorodecylmethyldichlorosilane is a high-purity, specialty organosilicon compound featuring a long perfluoroalkyl chain, making it a key intermediate for imparting exceptional surface properties. This chemical is critical for creating durable, hydrophobic, and oleophobic coatings with high chemical and thermal resistance. It is primarily utilized by manufacturers in the advanced materials, electronics, and specialty chemical sectors seeking to develop high-performance surface treatments and functional polymers.

Application

• Surface Modification Agent: Used to create superhydrophobic and oleophobic coatings on glass, metals, ceramics, and textiles for self-cleaning, anti-fouling, and anti-icing applications.
• Silicone & Polymer Synthesis: Serves as a key monomer or modifier in the synthesis of fluorinated silicones and specialty polymers, enhancing their chemical inertness, thermal stability, and low surface energy.
• Electronics & Semiconductor Industry: Employed in the formulation of protective coatings for micro-electromechanical systems (MEMS), optical fibers, and electronic components to provide moisture and chemical barrier properties.
• Release Coatings & Mold Agents: Used to formulate high-performance, non-stick release coatings for industrial molds and liners, particularly where extreme conditions are present.
• Adhesion Promoters: Acts as a coupling agent to improve the adhesion between inorganic substrates (like glass or metal) and organic polymers or resins in composite materials.
• Research & Development: A valuable building block for academic and industrial R&D in nanotechnology, advanced coatings, and novel fluorinated material science.

Quality Control

Our production of 1H,1H,2H,2H-Perfluorodecylmethyldichlorosilane adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including GC, NMR, and FTIR, to verify identity, purity, and the absence of critical impurities. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. This material is hygroscopic (moisture-sensitive) and reacts vigorously with water, alcohols, and bases. It is recommended to handle and store under an inert atmosphere (e.g., nitrogen or argon) to maintain purity and prevent hydrolysis. Keep away from strong acids and organic solvents. Recommended storage temperature: 2-8°C for long-term stability.
