Description

Vinyl(3,3,3-Trifluoropropyl)Dimethylsilane is a specialized organosilicon monomer featuring a reactive vinyl group and a fluorinated alkyl chain. This unique structure makes it a critical building block for synthesizing advanced silicone polymers with enhanced surface properties, including exceptional oil and solvent resistance, low surface energy, and improved thermal stability. It is primarily sought by R&D chemists and process engineers in the silicone manufacturing, specialty coatings, and advanced materials sectors for developing high-performance release agents, hydrophobic coatings, and fluorosilicone elastomers.

Application

• Fluorosilicone Polymer Synthesis: A key monomer for producing fluorosilicone rubbers and resins, imparting fuel, oil, and chemical resistance.
• Specialty Release Coatings: Used in formulations for high-performance, non-stick release liners in adhesive tapes and industrial molding processes.
• Surface Modification Agents: Employed to create hydrophobic and oleophobic surfaces on textiles, glass, and metals.
• Adhesive & Sealant Additives: Enhances the environmental resistance and durability of silicone-based adhesives and sealants.
• Pharmaceutical & Cosmetic Intermediates: Serves as a precursor for synthesizing specialized silane coupling agents used in controlled delivery systems.
• Optical Fiber Coatings: Contributes to protective coating layers that require specific refractive indices and environmental protection.

Quality Control

Our Vinyl(3,3,3-Trifluoropropyl)Dimethylsilane is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR), to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing purity, identity, and key physical properties 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). Due to its highly volatile nature, keep away from heat, sparks, and open flames. Use under an inert atmosphere (e.g., nitrogen or argon) for extended storage or after opening to maintain product integrity.
