Description

1,2-Bis(Dichloromethylsilyl) Ethene is a specialized organosilicon compound that serves as a critical building block in advanced material synthesis. Its unique molecular structure, featuring two reactive dichloromethylsilyl groups, makes it a versatile precursor for creating cross-linked siloxane networks and functionalized polymers. This compound is essential for R&D and production in industries focused on high-performance silicones, ceramic precursors, and tailored surface coatings. Its controlled reactivity is key to developing materials with specific thermal, mechanical, and chemical resistance properties.

Application

• Silicone Polymer Cross-linking Agent: Used to introduce cross-links into silicone resins and elastomers, enhancing their thermal stability and mechanical strength.
• Preceramic Polymer Synthesis: Acts as a key monomer in the production of silicon carbide (SiC) or silicon oxycarbide (SiOC) ceramic precursors via polymer-derived ceramic routes.
• Surface Modification Reagent: Employed to graft functional silane layers onto inorganic surfaces like glass, silica, or metals for improved adhesion or specific surface properties.
• Specialty Silicone Intermediate: Serves as a reactive intermediate in the synthesis of custom siloxane oligomers and dendritic structures for niche applications.
• Adhesive & Sealant Formulations: Incorporated into high-performance formulations to improve cure profiles and final product durability.
• Research & Development: A valuable tool in academic and industrial labs for exploring new organosilicon chemistry and novel hybrid materials.

Quality Control

Every batch of 1,2-Bis(Dichloromethylsilyl) Ethene is manufactured and tested under stringent quality management protocols to ensure consistency and reliability for your processes. We employ advanced analytical techniques, including GC, NMR, and Karl Fischer titration, to verify critical parameters such as purity, identity, and moisture content. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and highly volatile nature, this material must be stored under a dry, inert atmosphere (e.g., nitrogen or argon) in a cool, well-ventilated area. Recommended storage temperature is 2-8°C to minimize degradation and volatility. Keep away from moisture, heat, and incompatible materials such as strong bases and oxidizers.
