N-(2-Aminoethyl)-3-Aminopropyltrimethoxysilane (AEAPTMS) is a bifunctional organosilane coupling agent primarily used to promote adhesion between inorganic surfaces and organic polymers. Due to its dual amino functionality and methoxy groups, AEAPTMS serves as a key component in a wide range of applications, including coatings, adhesives, sealants, composites, and surface modification processes.
The global AEAPTMS market is projected to grow at a CAGR of 6.1% from 2025 to 2031, driven by its increasing use in construction materials, advanced composites, electronics, and biomedical coatings. The rise in demand for high-performance surface treatment chemicals and adhesion promoters in industrial processes is further fueling market growth.
N-(2-Aminoethyl)-3-Aminopropyltrimethoxysilane is a versatile silane coupling agent with enhanced reactivity due to its two primary amino groups. It is used to enhance the bonding between inorganic substrates (such as glass, silica, or metal oxides) and organic resins (epoxies, polyurethanes, etc.).
