Description

Trichloro(1,1,2,2-Tetrafluoroethyl)Silane is a highly reactive organosilicon compound that serves as a critical building block for introducing fluorinated alkylsilane functionality. This compound matters for its ability to impart unique surface properties, such as enhanced hydrophobicity, oleophobicity, and chemical resistance, to materials. It is primarily needed by manufacturers in the advanced materials, electronics, and specialty chemical sectors for creating high-performance coatings, modifying surfaces, and synthesizing novel fluorinated polymers.

Application

• Surface Modification Agent: Used to create hydrophobic and oleophobic coatings on glass, metals, and ceramics for anti-fouling, anti-staining, and easy-clean applications.
• Silicone Intermediate: Acts as a key monomer or cross-linker in the synthesis of specialty fluorosilicone polymers with enhanced thermal stability and solvent resistance.
• Electronics Manufacturing: Employed in the semiconductor industry for low-k dielectric materials, passivation layers, and as a precursor in chemical vapor deposition (CVD) processes.
• Adhesive & Sealant Formulation: Imparts improved environmental resistance and adhesion properties to high-performance sealants and adhesives.
• Pharmaceutical & Agrochemistry Intermediates: Serves as a versatile synthon for introducing the (1,1,2,2-tetrafluoroethyl)silane moiety into more complex bioactive molecules.
• Nanomaterial Functionalization: Used to modify nanoparticles (e.g., silica, metal oxides) to alter their dispersion characteristics and compatibility with fluorinated matrices.

Quality Control

Our Trichloro(1,1,2,2-Tetrafluoroethyl)Silane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and NMR spectroscopy, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Recommended storage temperature is 2-8°C for long-term stability.
