Description

2-[[3-(Chlorodimethylsilyl)Propoxy]Methyl]Oxirane is a specialized organosilicon compound featuring both an epoxide (oxirane) ring and a chlorosilane functional group. This unique bifunctional structure makes it a valuable reactive intermediate for creating advanced silicone polymers and hybrid organic-inorganic materials. It is primarily used by R&D chemists and process engineers in the silicone, adhesive, and specialty coatings industries to introduce cross-linking sites and enhance material properties.

Application

• Silicone Cross-Linking Agent: Used to introduce reactive epoxide sites into silicone polymers for heat-curable or UV-curable systems.
• Adhesive & Sealant Formulation: Serves as a key monomer or adhesion promoter in high-performance epoxy-silicone hybrid adhesives and sealants.
• Surface Modification: Employed as a silane coupling agent to functionalize inorganic surfaces (glass, metals, fillers) with epoxy groups for improved composite bonding.
• Specialty Resin Synthesis: A building block for synthesizing novel epoxy-functional silicone resins used in protective and release coatings.
• Pharmaceutical & Cosmetic Intermediates: Used in the research and development of siloxane-based drug delivery systems and cosmetic ingredients.
• Electronics Encapsulation: A component in formulating silicone encapsulants and potting compounds for electronic device protection.

Quality Control

Our production of 2-[[3-(Chlorodimethylsilyl)Propoxy]Methyl]Oxirane adheres to strict internal quality standards to ensure batch-to-batch consistency and reliability. Each lot is analyzed using advanced techniques including GC, NMR, and titration to verify critical parameters such as purity, chlorosilane content, and epoxide value. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 15-25°C. Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and maintain product integrity. Keep away from heat, sparks, and open flame.
