Description
3-Aminopropyltriethoxysilane (CAS 919-30-2) is an aminosilane coupling agent sold under trade names including AMEO, A-1100, A-1112, AGM 9, and NUCA 1100. It carries no E-code designation. The molecule combines a reactive alkoxysilane group with a primary amine, enabling covalent bonding between inorganic substrates and organic polymer matrices.
In epoxy and polyurethane coatings, it bonds mineral fillers and glass fibers to the resin network by hydrolyzing to form silanol groups that condense with surface hydroxyl groups, while the amine reacts directly into the polymer backbone. In personal care formulations, it functions as a hair and skin conditioner by adsorbing onto keratin surfaces through electrostatic and covalent interactions.
This product is supplied as a neat liquid and is registered under REACH (EC 213-048-4), classified under HS code 29310095. No FCC or Ph.Eur. monograph applies. Standard packaging includes drums and IBCs; documentation including SDS and CoA is available upon request.
