Description

Vinylethyldichlorosilane is a highly reactive organosilicon compound, specifically a dichlorosilane derivative with both vinyl and ethyl functional groups. This dual functionality makes it a versatile intermediate for introducing silicon-based cross-linking sites and organic side chains into polymers and advanced materials. It is essential for manufacturers in the silicone, specialty polymer, and advanced materials sectors seeking to modify surface properties and enhance material performance.

Application

• Silicone Polymer Synthesis: A key monomer or intermediate for producing modified silicone resins, elastomers, and fluids with specific organic side chains.
• Surface Modification Agent: Used as a coupling agent or primer to functionalize inorganic surfaces (glass, metals, silica) for improved adhesion of organic coatings.
• Cross-linking Agent: Employed in the production of cross-linked silicone networks, contributing to heat-resistant and durable materials.
• Intermediate for Silane Coupling Agents: Serves as a precursor for synthesizing more complex silane coupling agents used in composite materials.
• Hydrophobic Coatings: A building block for creating water-repellent and anti-corrosive surface treatments.
• Adhesive & Sealant Formulations: Imparts specific reactivity and properties to silicone-based adhesives and sealants.
• Pharmaceutical & Agro-chemical Intermediates: Used in the synthesis of more complex organosilicon molecules for specialized applications.

Quality Control

Our Vinylethyldichlorosilane is produced under stringent process controls to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing, including Gas Chromatography (GC) and FT-IR spectroscopy. A Certificate of Analysis (COA) detailing purity, identity, and key physical properties is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and hygroscopic nature, store 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 maintain stability. Keep away from moisture, strong bases, and oxidizing agents.
