D.E.H.™ 29

D.E.H.™ 29 Epoxy Curing Agent is an economical, complex mixture of linear, branched and cyclic ethylene amines that offers more flexibility versus DETA, TETA, and TEPA type materials. It is recommended for epoxy coal tar systems, patch kits, two-pack adhesives, and other applications where color is not a limitation.

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
  • Higher peel strength
