Description

Trichloro[3-(1,1,2,2-Tetrafluoroethoxy)Propyl]Silane is a highly reactive organosilicon compound featuring a unique fluorinated ether side chain. This specialized silane is a critical intermediate for introducing hydrophobic, oleophobic, and low surface energy properties into advanced materials. It is essential for manufacturers in the semiconductor, specialty coatings, and high-performance polymer industries seeking to enhance material performance and durability.

Application

• Surface Modification Agent: Key precursor for synthesizing fluorinated silane coupling agents used to modify glass, metal, and silicon wafer surfaces.
• Semiconductor Manufacturing: Used in vapor-phase deposition processes to create hydrophobic, low-k dielectric or anti-stiction layers on microelectromechanical systems (MEMS) and integrated circuits.
• Specialty Coatings & Resins: Serves as a building block for fluorosilicone resins and coatings that require exceptional chemical resistance, water repellency, and thermal stability.
• Adhesive & Sealant Formulation: Incorporated to improve the adhesion and environmental resistance of high-performance silicone-based adhesives and sealants.
• Nanomaterial Functionalization: Used to graft fluorinated organic chains onto silica nanoparticles and other nanomaterials for advanced composite applications.
• Pharmaceutical & Agro-chemical Intermediates: Acts as a versatile synthon for introducing the silane and fluorinated ether moiety into more complex bioactive molecules.

Quality Control

Our Trichloro[3-(1,1,2,2-Tetrafluoroethoxy)Propyl]Silane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and Karl Fischer titration, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and reacts vigorously with strong acids and organic solvents. Keep away from heat, sparks, and open flame. Use under an inert atmosphere (e.g., nitrogen or argon) for extended storage or handling to prevent hydrolysis.
