D.E.H 29 Aliphatic polyamine Dow Chemical Crosslinking / Coupling / Curing Agents >> Amines /Amides >> aliphatic Epoxy (EP) ADHESIVE 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. Adhesives Lows cost aliphatic polyamine curing agent. Similar in characteristics to DETA and TETA. Offers good flexibility. Used in two-pack adhesives. Yields much higher peel strength than DETA or TETA at comparable geltimes and lower cost.
