  • Applications

    N,N-Bis(2-hydroxyethyl)-p-toluidine (CAS 3077-12-1) is used as a reactive amine component in epoxy resin systems, commonly acting as a curing agent or co-curing modifier to adjust cure behavior and epoxy compatibility. It may function as a crosslinking modifier or chain extender in polyurethane/polyurea coatings and adhesives. It also serves as an intermediate in the synthesis of specialty dyes and colorant additives, and as a building block in polymer formulations seeking functional groups. In coatings and inks formulations, its hydroxyl groups and aromatic amine core can contribute to adhesion and post-cure properties. Its use is dependent on local regulations and formulation limits.
