Tetraethylenepentamine (TEPA) is widely used as a curing agent in epoxy resins, enhancing their mechanical and thermal properties for applications in coatings, adhesives, and composites. It serves as a chelating agent in water treatment processes, effectively binding and removing heavy metal ions from industrial wastewater. In the oil and gas industry, TEPA is employed as a corrosion inhibitor, protecting pipelines and equipment from degradation. It also acts as a surfactant and emulsifier in various industrial formulations, improving stability and performance. Additionally, TEPA is utilized in the synthesis of specialty chemicals, including lubricant additives and pharmaceuticals, due to its versatile reactivity and functional groups.
