Description

Bis((Tridecafluoro-1,1,2,2-Tetrahydrooctyl)Dimethylsiloxy)Methylsilane is a high-performance fluorinated organosilicon compound engineered to deliver exceptional surface energy reduction and chemical resistance. This advanced material is critical for formulating durable, low-surface-tension coatings and release agents that perform in demanding environments. It is primarily sought by manufacturers in the coatings, sealants, and specialty chemical industries seeking to enhance product performance with reliable, high-purity intermediates.

Application

• Fluorinated Silicone Oil & Grease Synthesis: A key monomer for producing high-performance fluorosilicone fluids and greases with superior thermal stability and chemical resistance.
• Water & Oil Repellent Coatings: Imparts excellent hydrophobic and oleophobic properties to surfaces for textiles, paper, and construction materials.
• Mold Release Agents: Used in formulations for high-temperature molding processes (e.g., rubber, plastics, composites) to ensure clean, consistent release.
• Surface Modification of Nanoparticles: Acts as a fluorosilane coupling agent to functionalize silica, titania, or other inorganic particles for dispersion in fluorinated matrices.
• Specialty Additives for Polymers: Incorporated into fluoropolymers or silicones to improve lubricity, reduce friction, and enhance weatherability.
• Electronic & Optical Materials: Used in the development of low-refractive-index coatings and protective layers for sensitive electronic components.

Quality Control

Our Bis((Tridecafluoro-1,1,2,2-Tetrahydrooctyl)Dimethylsiloxy)Methylsilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, GC, and FTIR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment 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 at 15-25°C. This material is hygroscopic (moisture-sensitive) and incompatible with strong bases and fluorides. Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation.
