Description

Dichloro(3-Chloropropyl)Silane is a versatile organosilicon compound that serves as a key intermediate in the synthesis of functional silanes and silicone polymers. Its bifunctional structure, featuring both hydrolyzable chloro groups and an organofunctional chloropropyl chain, makes it a critical building block for introducing reactive sites into materials. This product is essential for manufacturers in the specialty chemicals, advanced materials, and electronics sectors seeking to develop products with tailored surface properties, adhesion promotion, or cross-linking capabilities.

Application

• Silicone Intermediate: A fundamental precursor for the synthesis of a wide range of functional silanes and silicone-based polymers.
• Surface Modification Agent: Used to treat inorganic fillers (e.g., silica, glass fibers) and surfaces to improve compatibility and adhesion with organic polymer matrices.
• Adhesion Promoter: Imparts bonding properties in sealants, adhesives, and coatings, particularly for challenging substrates.
• Cross-linking Agent: Functions as a reactive site for creating cross-linked networks in silicone rubbers and resins, enhancing thermal and mechanical stability.
• Chemical Grafting: Serves as a linker molecule for attaching organic functional groups to silicon-based backbones in advanced material research.
• Electronics & Semiconductor: Used in the production of dielectric materials and protective coatings in microelectronics fabrication.

Quality Control

Our Dichloro(3-Chloropropyl)Silane is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC (Gas Chromatography) for purity and identity confirmation, to ensure it meets precise specifications for industrial and research applications. A Certificate of Analysis (COA) detailing all quality parameters is provided with every shipment to guarantee traceability and compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat and incompatible materials such as strong bases, oxidizing agents, and water. Due to its moisture-sensitive (hygroscopic) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature is 2-8°C for extended stability.
