Description

1,1,3,3-Tetramethyl-1,3-Bis(Pentafluorophenyl)Propanedisiloxane is a specialized organosilicon compound featuring a disiloxane backbone with pentafluorophenyl substituents. This structure is critical for its role as a high-performance precursor and intermediate in advanced material synthesis. It is primarily needed by R&D and manufacturing sectors focused on developing fluorinated silicones, specialty polymers, and surface-modifying agents where thermal stability and chemical resistance are paramount.

Application

• Key intermediate in the synthesis of fluorinated silicone polymers and resins for high-performance applications.
• Precursor for surface modification agents and coatings, imparting hydrophobic and oleophobic properties.
• Building block in advanced material research, particularly for heat-resistant and chemically inert elastomers.
• Used in the development of specialty release agents and lubricants for demanding industrial environments.
• Component in pharmaceutical and agrochemical intermediates requiring fluorinated siloxane chemistry.
• Starting material for adhesives and sealants designed for extreme temperature and chemical exposure.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized using advanced analytical techniques to confirm identity, purity, and consistency. Certificates of Analysis (COA) documenting key specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
