Description

Bis(3,3,3-Trifluoropropyl)Dichlorosilane is a highly reactive organosilicon compound that serves as a critical intermediate in the synthesis of advanced fluorinated silicone materials. Its unique structure, featuring two trifluoropropyl groups, imparts exceptional chemical resistance, thermal stability, and low surface energy to the resulting polymers. This product is essential for manufacturers in the specialty chemicals, electronics, and high-performance materials sectors seeking to develop products with superior hydrophobic, oleophobic, and release properties.

Application

• Key Intermediate for Fluorosilicone Polymers: Primary building block for the production of fluorosilicone oils, rubbers, and resins, which are valued for their fuel, oil, and solvent resistance.
• Surface Modification Agents: Used to create water- and oil-repellent coatings for textiles, paper, and optical components.
• Adhesive & Sealant Formulations: Imparts enhanced chemical and environmental stability to high-performance adhesives and sealants used in aerospace and automotive applications.
• Electronic Encapsulants: A precursor for materials that protect sensitive electronic components from moisture and corrosive atmospheres.
• Release Coatings: Manufacture of non-stick coatings for industrial molds and liners.
• Specialty Monomers: Serves as a starting material for synthesizing other functionalized silanes and siloxanes with tailored properties.

Quality Control

Our Bis(3,3,3-Trifluoropropyl)Dichlorosilane is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, identity confirmation, and impurity profiling. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to meet specific customer requirements and internal quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases, oxidizers, and moisture. Due to its highly volatile and moisture-sensitive nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) and handle in a controlled, dry environment. Typical recommended storage temperature is 2-8°C to maintain stability.
