D.E.H 29 Aliphatic polyamine Dow Chemical Crosslinking / Coupling / Curing Agents >> Amine Epoxy Resins Marine /Anti-Corrosive / Protective >> Marine Marine /Anti-Corrosive / Protective >> Heavy duty (anti-corrosive) D.E.H.* 29 epoxy curing agent is a liquid aliphatic polyamine curing agent. D.E.H. 29 curing agent is a low cost, aliphatic polyamine similar in characteristics to DETA(D.E.H. 20) and TETA(D.E.H. 24). D.E.H. 29 epoxy curing agent, however, offers more flexibility. It is recommended for epoxy coal tar systems, patch kits, two-pack adhesives, and other applications where color is not a limitation. In adhesives, D.E.H. 29 curing agent yields much higher peel strength than DETAor TETAat comparable geltimes and lower cost. marine and protective coatings Lows cost aliphatic polyamine curing agent. Used in marine and protective coatings. Offers good flexibility.
