Description

Tetrakis(Trifluoroacethoxy)Silane is a highly reactive organosilicon compound characterized by its four trifluoroacetate ester groups bonded to a central silicon atom. This structure makes it a valuable precursor and intermediate in advanced materials synthesis, particularly where the introduction of silicon and fluorine functionalities is required. It is essential for R&D and production in industries focused on specialty polymers, surface modification, and high-performance coatings.

Application

• Precursor for Silicone Polymers: Serves as a key monomer or cross-linking agent in the synthesis of fluorinated silicone resins and elastomers with enhanced chemical and thermal resistance.
• Surface Modification Agent: Used to functionalize inorganic surfaces (e.g., glass, silica, metals) to impart hydrophobic and oleophobic properties.
• Intermediate for Pharmaceutical & Agrochemistry: Acts as a building block in the synthesis of complex molecules requiring silicon-containing motifs for active ingredients or prodrugs.
• Adhesion Promoter in Coatings: Enhances the bonding of fluoropolymer coatings and sealants to various substrates.
• Research & Development: A critical reagent in academic and industrial labs for exploring new organosilicon chemistry and material science applications.
• Electronic Materials: Investigated for use in the deposition of silicon-containing thin films for microelectronics via chemical vapor deposition (CVD) or atomic layer deposition (ALD) techniques.

Quality Control

Our Tetrakis(Trifluoroacethoxy)Silane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including NMR, FT-IR, and GC/HPLC to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, moisture content, and other critical parameters is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) in its original sealed packaging to prevent degradation. Keep away from heat, open flames, and incompatible materials such as strong bases and oxidizing agents.
