D.E.H.™ 24

D.E.H. 24 Epoxy Curing Agent is an economical aliphatic polyamine hardener,triethylenetetraamine (TETA), that offers a short pot-life and cures in minutes with standard unmodified liquid epoxy resins. It is primarily used for civil engineering applications, maintenance paints and in the manufacture of epoxy-amine adducts.

Used in:

  • Adhesives
  • Casting and tooling
  • Civil Engineering
  • Composites
  • Marine and Protective Coatings
  • Potting and Encapsulation

Advantages:

  • Low viscosity
  • Economical
  • Cures in minutes
  • High chemical and solvent resistance
  • Can be modified to form a variety of other curatives
  • Low vapor hazard

Typical Properties
These properties are typical but do not constitute specifications.
