3-(2-Aminoethylamino)propyltrimethoxysilane (AEAPS) is a bifunctional silane coupling agent used to enhance adhesion between organic polymers and inorganic materials, improving mechanical properties in composites, adhesives, and coatings. It features an amino group for polymer bonding and a trimethoxysilane group for silica or glass surface reactivity, making it ideal for fiberglass reinforcement, rubber modification, and epoxy systems. This chemical has a CAS number of 1760-24-3, molecular formula C8H22N2O3Si, and a molecular weight of 222.36. It is stored at ambient conditions but requires careful handling due to its Danger classification (causes skin irritation and serious eye damage, may cause an allergic skin reaction, is harmful if inhaled, may cause damage to organs through prolonged or repeated exposure, and is toxic to aquatic life). Molekula supplies 3-(2-Aminoethylamino)propyltrimethoxysilane from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
