Description

1H,1H,2H,2H-Perfluorooctylmethyldichlorosilane is a high-purity, reactive organosilicon compound featuring a long perfluorinated alkyl chain, making it a key intermediate for imparting exceptional surface properties. This compound is critical for creating durable, low-surface-energy coatings with outstanding oil, water, and chemical repellency. It is primarily utilized by manufacturers in the advanced materials, electronics, and specialty textiles sectors seeking to develop high-performance, functionalized surfaces.

Application

• Surface Modification Agent: Used to create hydrophobic and oleophobic coatings on glass, ceramics, and metals for self-cleaning and anti-fouling applications.
• Electronics & Semiconductor Processing: Employed as a precursor for low-k dielectric materials and as a surface passivation layer to protect sensitive components.
• Textile & Fiber Treatment: Imparts durable water and oil repellency (DWR/DOR) to technical fabrics, protective clothing, and filtration media.
• Release Coatings: Serves as a key component in formulating non-stick and easy-release coatings for industrial molds and liners.
• Adhesion Promotion: Functions as a coupling agent to improve the adhesion between fluorinated polymers and inorganic substrates.
• Nanoparticle Functionalization: Used to modify the surface of silica and other nanoparticles to enhance dispersion in fluorinated matrices.

Quality Control

Our 1H,1H,2H,2H-Perfluorooctylmethyldichlorosilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and FTIR, to ensure high purity and consistent performance for demanding industrial applications. Certificates of Analysis (COA) detailing purity, identity, and key impurity profiles are available upon request.

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 reacts with strong acids and organic solvents; ensure containers are sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity.
