Triethylenetetramine (TETA)

Description

What is Triethylenetetramine (TETA)?

Triethylenetetramine (TETA) is a clear, viscous liquid amine with strong alkalinity and high reactivity. It is widely used as a curing agent (Hardener) for epoxy resins, a chelating agent, and an intermediate in chemical synthesis. Its excellent solubility, reactivity, and stability make it a critical raw material across multiple industries including coatings, adhesives, lubricants, and water treatment.
