Polyamines are used as chemical intermediates or functional additives in several industries:
-
Water Treatment: Used as coagulants/flocculants in treating wastewater.
-
Epoxy Curing Agents: Act as hardeners in epoxy resins (especially in paints, adhesives, and coatings).
-
Corrosion Inhibitors: Prevent rust in industrial systems.
-
Oil & Gas: Used in drilling fluids and refining processes.
-
Paper Industry: Help with wet strength and retention in papermaking.
