Amivion TEPA is a multifunctional aliphatic amine based on tetraethylenepentamine, containing five nitrogen atoms and seven reactive amine hydrogens per molecule. This high functionality enables efficient cross-linking with epoxy resins and supports a wide range of industrial reactions requiring multiple amine reactive sites. Amivion TEPA is used as an epoxy curing agent, as a key intermediate in polyamide and polyimide resin synthesis, in paper wet-strength resin production, and in corrosion inhibitor and fabric conditioner formulations. Its complete miscibility with water and strong basicity make it well suited to aqueous and solvent-borne chemical processes.
Key Features
- High Amine Functionality: With five nitrogen atoms and seven active amine hydrogens per molecule, Amivion TEPA offers a high density of reactive sites for cross-linking, chelation, and intermediate synthesis. This multifunctionality supports dense network formation in cured epoxy systems and versatile reactivity in chemical synthesis.
- Effective Epoxy Curing Performance: Amivion TEPA reacts with epoxide groups to form tightly cross-linked thermoset networks with good mechanical strength, chemical resistance, and adhesion. It is suitable for use in ambient and elevated temperature cure formulations, particularly where high cross-link density is required.
- Key Intermediate for Polyamide Resins: Amivion TEPA is widely used as a building block in the synthesis of polyamide resins for printing inks, adhesives, and paper wet-strength applications. Its chain length and amine content make it effective for producing polyamides with tailored molecular weights and softening points.
- Strong Chelating Capacity: The multiple nitrogen atoms in Amivion TEPA enable it to coordinate with metal ions, making it useful as a chelating agent precursor in water treatment, metal surface treatment, and detergent formulations.
- Water Miscibility and Process Flexibility: Amivion TEPA is fully miscible with water, supporting use in aqueous formulations including waterborne coatings, paper additives, and industrial process chemicals. This solubility facilitates dilution, blending, and application in water-based systems.
Typical Applications
Amivion TEPA is used as a reactive epoxy curing agent in adhesives, protective coatings, and construction materials, where its high amine functionality contributes to cross-link density and chemical resistance in the cured system. It is also a key starting material in the production of polyamide resins for printing ink and adhesive applications, and in the synthesis of polyimides for high-performance engineering materials.
In the paper industry, Amivion TEPA serves as an intermediate in the synthesis of wet-strength resins that improve paper durability under moist conditions. Additional applications include fabric softener and textile auxiliary production, corrosion inhibitor formulations for metal surface treatment and oil field applications, chelating agent synthesis, and fuel and lubricant additive chemistry.
