Description

1H,1H,2H,2H-Perfluoropentyltrimethoxysilane is a high-purity fluorinated organosilane coupling agent, essential for imparting exceptional water, oil, and stain repellency to surfaces. Its unique perfluorinated chain provides superior surface energy reduction and chemical resistance, making it a critical component in advanced material formulations. This product is primarily needed by manufacturers in the coatings, textiles, electronics, and specialty chemical industries seeking to develop high-performance, durable surface treatments.

Application

• Surface Modification Agent: Used to create hydrophobic and oleophobic coatings on glass, ceramics, and metals for anti-fouling and easy-clean applications.
• Textile Finishing: Imparts durable water and oil repellency (DWR) to technical fabrics, outdoor gear, and protective clothing.
• Electronics Protection: Serves as a moisture barrier and anti-stiction coating for micro-electromechanical systems (MEMS), sensors, and circuit boards.
• Stone and Masonry Sealant: Provides deep-seated protection against water, oil, and graffiti for architectural stone, concrete, and tile.
• Paper and Packaging Treatment: Used to create grease-resistant and moisture-barrier coatings for food packaging and specialty papers.
• Adhesion Promoter: Enhances the bonding between fluoropolymers and various substrates in composite materials.
• Optical Coatings: Applied to lenses and displays to provide anti-fogging, anti-reflective, and self-cleaning properties.

Quality Control

Our 1H,1H,2H,2H-Perfluoropentyltrimethoxysilane 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. Certificates of Analysis (COA) detailing purity, identity, and key physical properties are provided with every shipment to guarantee compliance with your technical requirements.

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 must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity.
