Description
N-(2-Aminoethyl)-3-aminopropyltrimethoxysilane (CAS 1760-24-3) is a diamine-functional silane coupling agent commercially known as Dow Corning Z-6020. It carries no assigned E-code and is identified under EC 217-164-6 with HS code 29310095.
In epoxy and polyurethane coatings, it bonds inorganic substrates to organic polymer matrices by reacting its methoxy groups with surface silanol groups while the diamine end cross-links or co-reacts with the resin. In electronics encapsulants and structural adhesives, this dual reactivity reduces delamination at glass and metal interfaces under thermal cycling.
The material is supplied as a neat liquid and is subject to REACH registration requirements within the EU. Procurement quantities typically range from drum to IBC formats. Buyers should request a current Safety Data Sheet and confirm supplier REACH compliance documentation before ordering.
