Description

1,1-Bis(Dimethylchlorosilyl)Ethane is a highly reactive organosilicon compound, specifically a bifunctional chlorosilane, that serves as a critical building block in advanced silicone chemistry. Its value lies in its ability to act as a versatile cross-linking agent and precursor for synthesizing specialized silicone polymers, resins, and silane coupling agents. This product is essential for manufacturers in the silicone elastomer, specialty coatings, and advanced materials industries seeking to enhance thermal stability, mechanical properties, and adhesion performance.

Application

• Silicone Cross-Linking Agent: A key intermediate for creating cross-linked silicone networks in high-performance elastomers, sealants, and resins.
• Precursor for Silane Coupling Agents: Used to synthesize novel bifunctional silanes that improve adhesion between organic polymers and inorganic surfaces like glass, metals, and minerals.
• Specialty Polymer Synthesis: Serves as a monomer or comonomer in the production of tailored polysiloxanes and polycarbosilanes with specific chain architectures.
• Surface Modification: Employed to functionalize silica, nanoparticles, and other fillers to enhance compatibility and dispersion in composite materials.
• Advanced Material Research: Utilized in R&D for developing new silicon-based ceramics (polymer-derived ceramics), coatings, and electronic materials.
• Hydrophobic Coatings: Acts as a starting material for creating water-repellent and corrosion-resistant surface treatments.

Quality Control

Our production of 1,1-Bis(Dimethylchlorosilyl)Ethane adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including Gas Chromatography (GC) and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is 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, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize volatility and degradation. Due to its highly volatile and moisture-sensitive nature, containers must be kept sealed under an inert atmosphere (nitrogen or argon) and handled in a dry environment to prevent hydrolysis. Keep away from strong acids, bases, and oxidizing agents.
