Description

2-(Dichloromethylsilyl)Ethyl Acetate is a specialized organosilicon compound featuring a reactive dichlorosilyl group and an ester functionality. This dual reactivity makes it a valuable versatile intermediate for synthesizing advanced silicone polymers and surface-modifying agents. It is primarily needed by manufacturers in the silicone, adhesives, and coatings industries for developing materials with tailored properties such as enhanced adhesion, hydrophobicity, and cross-linking density.

Application

• Silicone Polymer Synthesis: A key monomer or cross-linking agent for producing specialty silicone resins, elastomers, and sealants with specific mechanical and chemical resistance properties.
• Surface Modification & Coupling Agent: Used to functionalize inorganic surfaces (e.g., glass, silica, metals) to improve the adhesion of organic polymers in composite materials and coatings.
• Adhesive & Sealant Formulations: Imparts moisture-curing characteristics and enhances bonding strength in high-performance industrial and construction adhesives.
• Hydrophobic Coatings: Serves as a precursor for creating water-repellent and anti-corrosive coatings on various substrates.
• Pharmaceutical & Agro-chemical Intermediates: Employed in the synthesis of more complex organosilicon molecules for specialized applications.
• Research & Development: Used in academic and industrial R&D for exploring new silicone-based materials and hybrid organic-inorganic systems.

Quality Control

Our production of 2-(Dichloromethylsilyl)Ethyl Acetate adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with each shipment to guarantee traceability and compliance with your specifications.

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 moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Keep away from heat, open flames, and incompatible materials such as strong bases and oxidizing agents.
