Description

Chlorodimethyl-3,3,3-Trifluoropropylsilane is a highly versatile organosilicon reagent featuring a reactive chlorosilane group and a fluorinated alkyl chain. This compound is essential for introducing hydrophobic, oleophobic, and chemically resistant trifluoropropyl functionalities onto surfaces and into polymer backbones. It is primarily sought by manufacturers in the silicone, coatings, and specialty chemical industries for developing advanced materials with tailored surface properties and enhanced performance.

Application

• Silicone Rubber & Elastomer Modification: Used as a key intermediate to incorporate trifluoropropyl groups into silicone polymers, significantly improving their resistance to fuels, oils, solvents, and chemicals.
• Surface Treatment & Coatings: Acts as a coupling agent or surface modifier to create durable, low-surface-energy, water- and oil-repellent coatings on glass, metals, and ceramics.
• Adhesive & Sealant Formulations: Enhances the chemical resistance and environmental stability of high-performance silicone-based adhesives and sealants.
• Pharmaceutical & Agrochemical Intermediates: Serves as a building block in the synthesis of more complex molecules for pharmaceutical and agrochemical applications, leveraging the unique properties of the fluorine atom.
• Release Coatings: Employed in the production of fluorosilicone release liners for pressure-sensitive adhesives, providing excellent release characteristics.
• Fiber & Textile Treatment: Imparts durable water and stain repellency to technical textiles and fibers.

Quality Control

Our Chlorodimethyl-3,3,3-Trifluoropropylsilane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, NMR, and FTIR to confirm identity and assay. A Certificate of Analysis (COA) detailing purity and impurity profiles is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong acids, bases, and oxidizing agents. Due to its highly volatile and moisture-sensitive nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain product integrity. Recommended storage temperature: 2-8°C for long-term stability.
