N,N'-Bis(3-aminopropyl)ethylenediamine (CAS 10563-26-5) is a multifunctional polyamine building block, widely used across high-demand industries thanks to its four reactive amino groups and strong alkaline properties. Nantong Lanpu Chemical supplies this product to epoxy resin manufacturers, polymer producers, textile factories, metal treatment facilities, and pharmaceutical research institutions worldwide, supporting core production and R&D processes with consistent, high-quality material. Below are its most critical and widely applied industrial uses:
1. Epoxy Resin Curing Agent
The largest and most vital application of N,N'-Bis(3-aminopropyl)ethylenediamine (CAS 10563-26-5) is as a high-performance epoxy resin curing agent and curing accelerator. Its four reactive amino groups rapidly react with epoxy groups to form a dense, three-dimensional crosslinked network, delivering exceptional mechanical strength, adhesion, corrosion resistance, and thermal stability to cured epoxy products.
It is widely used in marine coatings, pipeline anti-corrosion treatments, electronic component potting, and structural adhesive formulations. When used as a co-curing agent, it effectively adjusts curing speed, improves compatibility with epoxy resins, and eliminates common defects like pinholes and cracking.
2. Polymer Synthesis & Modification
In polymer manufacturing, N,N'-Bis(3-aminopropyl)ethylenediamine (CAS 10563-26-5) serves as a key monomer and crosslinking agent for polyamide, polyurethane, and polyurea synthesis. In polyurethane production, it acts as a chain extender and crosslinker, optimizing the balance between hardness and elasticity in foam, elastomer, and coating products. For polyamide resins, it improves heat resistance and hydrolysis stability, making the final product suitable for high-performance engineering plastic and synthetic fiber applications.
3. Metal Surface Treatment & Corrosion Inhibition
N,N'-Bis(3-aminopropyl)ethylenediamine (CAS 10563-26-5) can adsorb firmly onto the surface of steel, copper, and aluminum alloys, forming a thin, protective molecular film that effectively blocks corrosion from moisture, acid, and salt. It is commonly added to cooling water systems, metal cleaning agents, and industrial lubricants to prevent rust and extend equipment service life. Additionally, it acts as a complexing agent in metal plating baths, improving plating uniformity and adhesion for high-quality surface finishing.
4. Textile & Leather Finishing Agent
In the textile and leather industry, this compound functions as a durable fixing agent and crosslinking agent for dyes and finishes. It forms stable covalent bonds with dye molecules and textile fibers, significantly improving color fastness, wash resistance, and light resistance of dyed fabrics. It also enhances the softness, wrinkle resistance, and water repellency of textiles and leather goods without affecting their breathability. As an environmentally friendly fixing agent alternative, it meets global textile safety and emission standards, supported by the consistent quality supplied by Nantong Lanpu Chemical.
5. Pharmaceutical & Organic Synthesis Intermediate
N,N'-Bis(3-aminopropyl)ethylenediamine (CAS 10563-26-5) is a valuable intermediate in fine chemical and pharmaceutical synthesis, used to construct complex nitrogen-containing molecular frameworks for active pharmaceutical ingredients (APIs), biological additives, and specialty surfactants. Its high reactivity and linear structure make it suitable for condensation, alkylation, and cyclization reactions, supporting the production of antiviral agents, antibacterial compounds, and chelating agents. High-purity grades from Nantong Lanpu Chemical comply with strict chemical synthesis standards, ensuring reaction efficiency and product purity.
