Curing Agents DETDA (Diethyltoluenediamine) CAS No. 68479-98-1 For Extended Pot Life and Final Cure Strength
DETDA (Diethyltoluenediamine) CAS No. 68479-98-1
1. Desciption
DETDA (Diethyltoluenediamine) is a crucial liquid aromatic diamine used as a fast-acting curative and chain extender in polyurethanes, polyureas, and epoxy systems, enhancing strength, chemical resistance, and toughness for coatings, elastomers (like wheels/bushings), and spray applications, functioning as a safer, liquid alternative to MOCA. It's a yellow/brown liquid with low viscosity, good handling, and helps achieve superior dynamic properties in demanding industrial uses, also serving as an intermediate for other chemicals.
