Description

n-[3-(Triethoxysilyl)Propyl]-2-Carbomethoxyaziridine CAS NO 193417-26-4 is a specialized organosilane coupling agent containing both a triethoxysilyl group and a reactive aziridine ring. This unique bifunctional structure makes it a critical intermediate for creating covalent bonds between inorganic substrates and organic polymer matrices. It is essential for industries requiring advanced surface modification, adhesion promotion, and the development of durable composite materials.

Application

• Adhesion Promoter: Enhances the bonding strength between inorganic fillers (glass, silica, metals) and organic polymer resins (epoxy, polyurethane, acrylic) in advanced composites and coatings.
• Surface Modification Agent: Used to functionalize the surface of nanoparticles, glass fibers, and minerals to improve dispersion and compatibility within polymer systems.
• Crosslinking Agent: Serves as a reactive monomer or co-monomer in polymer synthesis, introducing crosslinks to improve thermal stability, chemical resistance, and mechanical properties of the final product.
• Coupling Agent for Sealants and Adhesives: Improves the durability, water resistance, and adhesion of high-performance sealants, adhesives, and elastomers, especially in demanding environments.
• Fiber Sizing: Applied as a key component in sizing formulations for glass and carbon fibers to optimize the fiber-matrix interface in reinforced plastics (FRP).
• Hybrid Material Synthesis: Facilitates the creation of organic-inorganic hybrid (OIH) materials, sol-gel coatings, and nanocomposites with tailored properties for optical, electronic, or protective applications.
