  • Applications

    N-Ethylaminoethanol (CAS 110-73-6) is widely used as a reactive intermediate and solvent in industrial formulations, underpinning the manufacture of surfactants and specialty chemicals and serving as a curing agent or co-reactant in epoxy and polyurethane systems. It functions as a solvent in coatings, inks, and adhesives, aiding resin dissolution and formulation stability, and can act as a reactive amine for epoxy curing. In polyurethane chemistry it can serve as a chain extender or crosslinking component. It is also used as a stabilizer and corrosion inhibitor in metalworking fluids and other cleaning formulations, helping control pH and metal corrosion. Additionally, it provides a starting point for synthesizing functionalized amines and other specialty additives used in a wide range of industrial products.
