Description

1H,1H,2H,2H-Perfluorooctyldimethylchlorosilane is a highly reactive organosilicon compound featuring a perfluorinated alkyl chain, making it a key intermediate for imparting exceptional surface properties. This chemical is crucial for creating durable, low-energy surfaces with outstanding oil, water, and stain repellency. It is primarily sought after by manufacturers in the advanced materials, electronics, and textile industries for surface modification and functionalization applications.

Application

• Surface Modification Agent: Used to create hydrophobic and oleophobic coatings on glass, ceramics, and metals for anti-fouling and self-cleaning surfaces.
• Electronics Manufacturing: Applied as a coupling agent or surface treatment for semiconductors, microelectromechanical systems (MEMS), and electronic components to enhance moisture resistance and performance.
• Textile Finishing: Imparts durable water and oil repellency (DWR) to technical fabrics, outdoor gear, and protective clothing.
• Stone & Masonry Protection: Serves as a key ingredient in formulations for protecting building materials like marble, granite, and concrete from water, oil, and graffiti.
• Paper & Packaging Treatment: Used to develop grease-resistant and moisture-barrier coatings for specialty papers and food packaging.
• Synthesis Intermediate: Acts as a vital precursor for synthesizing more complex fluorinated silanes, polymers, and specialty surfactants.

Quality Control

Our 1H,1H,2H,2H-Perfluorooctyldimethylchlorosilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements of industrial and R&D applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment.

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). This material is hygroscopic (moisture-sensitive) and must be handled under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain product integrity.
