Description

Trichloro(1,1,2,2,3,3,4,4-Octafluorobutyl)Silane is a specialized organosilicon compound featuring a perfluorinated butyl chain, making it a valuable precursor for introducing fluorinated alkyl groups onto surfaces or into polymers. This compound matters for its ability to impart low surface energy, chemical resistance, and hydrophobic/oleophobic properties to materials. It is primarily needed by manufacturers in the advanced materials, electronics, and specialty coatings sectors seeking to engineer surfaces with specific performance characteristics.

Application

• Surface Modification Agent: Used to create hydrophobic and oleophobic coatings on glass, metals, and ceramics for anti-fouling, anti-stain, and self-cleaning applications.
• Synthesis of Fluorinated Silicones: Serves as a key monomer or intermediate in the production of high-performance fluorosilicone polymers with enhanced solvent and fuel resistance.
• Adhesion Promoter: Functions as a coupling agent to improve the bonding between fluorinated materials and inorganic substrates in composite manufacturing.
• Semiconductor and Microelectronics: Employed in the vapor-phase deposition of low-k dielectric films or as a surface passivation layer to protect sensitive components.
• Release Coatings: Utilized in the formulation of non-stick and easy-release coatings for industrial molds and liners.
• Water and Oil Repellent Textiles: Applied to treat fabrics and fibers to achieve durable water and oil repellency (DWR/DOR).
