N-[3-(Trimethoxysilyl)propyl]ethylenediamine

N-[3-(Trimethoxysilyl)propyl]ethylenediamine, with CAS No. 1760-24-3 and chemical formula C₈H₂₂N₂O₃Si, appears as a colorless to pale yellow transparent liquid, which is an important diamino silane coupling agent. Its core function is to connect organic and inorganic materials. The diamino and methoxy bifunctional groups in the molecule can react with organic resins and inorganic substrates respectively to improve the interfacial bonding force of materials. It is widely used in composite materials, coatings, adhesives and other fields, which can enhance the adhesion between glass fibers and resins, improve the dispersibility of fillers in coatings, and increase the bonding strength of adhesives to metals and ceramics. In addition, it is used for surface modification of nanomaterials, preparation of adsorbents for wastewater treatment and precursors of bioimaging materials, and is a key chemical raw material for improving the comprehensive performance of materials in industrial production.
