Hexatran™ (TAN-Triaminononane) is a unique trifunctional primary amine molecule and is available in a wide range of grades.

Hexatran delivers performance equal to or better than other amines used in epoxies or asphalt because of its low odor profile and consistent quality. Hexatran provides a consistent raw material basis compared to other amines (TEPA, TETA, DETA) typically used in these applications. Hexatran can be functionalized to control the curing process.

Application end uses


  • Hexatran's three primary amines provide improved curing time, chemical resistance and excellent flex.
  • Hexatran's chemical structure makes it a good replacement or supplement for other amines such as TETA, TEPA, DETA and IPDA.
  • Hexatran can be easily modified into other key derivatives for the epoxy marketplace.


  • Hexatran is used in liquid anti-strip to promote better adhesion of asphalt to aggregate.
  • Hexatran has better performance when compared to other amines.
  • Hexatran's low viscosity and low odor make it easier to work with during production and application.
  • Hexatran and its derivatives are used as ionic and non-ionic emulsifiers.


  • Hexatran's unique aliphatic structure provides alternate routes to carbamates and isocyanates.
  • Isocyanates produced from Hexatran have low viscosity at high solids, promoting easy workability.
  • Urethanes produced using Hexatran have great chemical and weather resistance that promote high adhesion and are non-yellowing.

Oil and gas:

  • Hexatran derivatives are used in scale inhibition, drilling fluid emulsifiers, vapor phase and film forming corrosion inhibition.
  • Hexatran is used to produce a semi-permanent clay/shale stabilizer with improved performance over choline chloride and potassium chloride (KCl) and with similar performance to hexamethylene diamine (HMD) but with superior permanence.
  • Hexatran derivatives can be used to remove hydrogen sulfide and carbon dioxide from gas streams.
