Description

1,6-Bis(Chlorodimethylsilyl)Hexane is a bifunctional organosilicon compound featuring reactive chlorosilane groups at both ends of a hexane spacer chain. This molecular architecture makes it a highly versatile cross-linking agent and key building block in silicone and polymer chemistry. It is primarily used by R&D chemists and process engineers in the specialty silicones, adhesives, and advanced materials sectors to create novel polymers with tailored properties.

Application

• Silicone Elastomer & Rubber Cross-linker: Serves as a chain extender or cross-linking agent to modify the mechanical properties, thermal stability, and network density of silicone polymers.
• Silicone Resin & Coating Precursor: Used in the synthesis of high-performance silicone resins for release coatings, protective films, and high-temperature resistant paints.
• Adhesive & Sealant Formulation: Acts as an adhesion promoter and moisture-cure component in specialty silicone-based adhesives and sealants.
• Hybrid Organic-Inorganic Material Synthesis: A crucial monomer for creating sol-gel derived materials, ORMOSILs (Organically Modified Silicates), and other hybrid composites.
• Surface Modification Agent: Used to functionalize inorganic surfaces (e.g., silica, glass) with organic groups for improved compatibility in composite materials.
• Pharmaceutical & Cosmetic Intermediate: Employed in the synthesis of specialized silicone derivatives for controlled release or sensory enhancement applications.
• Research & Development: A valuable tool in academic and industrial R&D for exploring new polymer architectures and silicon chemistry.

Quality Control

Our production of 1,6-Bis(Chlorodimethylsilyl)Hexane adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis, including assay by GC or titration and impurity profiling. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and highly volatile nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and oxidizing agents.
