Description

Triethoxy[5,5,6,6,7,7,7-Heptafluoro-4,4-Bis(trifluoromethyl)heptyl]silane is a highly fluorinated organosilicon compound, specifically a fluoroalkylsilane, designed to impart exceptional surface properties. This specialty chemical is valued for its ability to deliver outstanding hydrophobicity, oleophobicity, and chemical resistance to treated substrates. It is a critical material for manufacturers in the advanced coatings, electronics, and specialty materials sectors seeking to engineer surfaces with low surface energy and enhanced performance.

Application

• Surface Modification Agent: Used to create hydrophobic and oleophobic coatings on glass, ceramics, metals, and polymers for anti-fouling, anti-stain, and easy-clean applications.
• Electronics & Semiconductor Processing: Serves as a key precursor for low-k dielectric materials and as a surface treatment to improve moisture resistance and adhesion in microelectronic components.
• Advanced Composite Materials: Functions as a coupling agent to improve the interfacial adhesion between fluorinated polymers or fillers and various matrices.
• Textile & Fiber Treatment: Imparts durable water and oil repellency (DWR) to technical textiles, outdoor apparel, and filtration media.
• Optical Coatings: Employed in the formulation of anti-reflective, anti-fog, and protective coatings for lenses, displays, and optical sensors.
• Stone & Masonry Protection: Used to formulate treatments that provide long-lasting water repellency and protection against weathering for architectural surfaces.
