Description

Ethylidenebis[Trichlorosilane] is a highly reactive organosilicon compound, primarily used as a key intermediate in the synthesis of specialized silicone polymers and silane coupling agents. Its value lies in its ability to introduce specific functional groups and cross-linking sites into polymer backbones, enhancing material properties like adhesion, thermal stability, and chemical resistance. This product is essential for manufacturers in the advanced materials, electronics, and specialty chemical sectors seeking to develop high-performance coatings, sealants, and composite materials.

Application

• Silicone Polymer Synthesis: A critical monomer for producing cross-linked and high-temperature resistant silicone resins and elastomers.
• Silane Coupling Agent Precursor: Used to manufacture custom silane coupling agents that improve the bond between organic polymers and inorganic surfaces like glass, metals, and minerals.
• Surface Modification: Imparts hydrophobic or specific reactive properties to surfaces for advanced coating applications.
• Electronic Materials: Serves as a starting material for silicon-containing precursors used in semiconductor manufacturing and protective coatings for electronic components.
• Adhesive & Sealant Formulation: Enhances the performance and durability of high-end industrial adhesives and sealants.
• Research & Development: A valuable building block in organic and polymer chemistry research for creating novel silicon-based materials.

Quality Control

Our Ethylidenebis[Trichlorosilane] is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay and impurity profile analysis via techniques such as GC and NMR. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. 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. Recommended storage temperature is 2-8°C to maintain stability.
