N-(2-Aminoethyl)-3-aminopropyltriethoxysilane Description
N-(2-Aminoethyl)-3-aminopropyltriethoxysilane (CAS 5089-72-5) is a colorless or slightly yellowish transparent liquid with a distinctive ammonia odor. It is soluble in alcohols, aliphatic, and aromatic hydrocarbons.
CAS 5089-72-5 is a difunctional amino silane containing reactive amino groups and hydrolyzable non-methoxysilane groups. This dual functionality allows it to effectively bond inorganic materials (such as glass, metals, and fillers) with organic polymers (like thermoplastics, thermosets, and elastomers).
This silane is widely used as a tackifier, surface modifier for organic/inorganic interfaces (providing anticorrosion and primer properties), and as an organosilicone polymer or cross-linking agent for moisture-curing polymers.

N-(2-Aminoethyl)-3-aminopropyltriethoxysilane: Guide
Triethoxysilane (TES), with the molecular formula C6H16O3Si, is a versatile silane compound that contains both hydrolyzable silicon-ethoxy bonds and active silicon-hydrogen bonds. These active silicon-hydrogen bonds are key raw materials for synthesizing various organic functional silanes.
For example, when reacted with acetylene, triethoxysilane produces highly selective vinyltriethoxysilane. When combined with chloropropylene, it yields high-purity γ-chloropropyltriethoxysilane. Triethoxysilane has numerous applications across industries, including surface modification, adhesion promotion, and the creation of specialized silane compounds.
