Description

N,N,N',N'-Tetrakis(3-Aminopropyl)-1,4-Butanediamine Polymer With 2-(Chloromethyl)Oxirane is a highly functional, branched polyamine-epichlorohydrin adduct, known for its dense network of reactive primary amine groups. This unique structure makes it an exceptional crosslinking agent, curing agent, and multifunctional modifier in advanced polymer systems. It is essential for industries requiring high-performance materials with enhanced mechanical strength, chemical resistance, and thermal stability, such as epoxy resin formulation, polyurethane chemistry, and specialty adhesives.

Application

• Epoxy Curing Agent: Functions as a high-functionality, low-temperature curing agent for epoxy resins, producing coatings, composites, and adhesives with excellent crosslink density and chemical resistance.
• Polymer Modification: Used as a chain extender or crosslinker in polyurethane and polyurea systems to improve tensile strength, hardness, and thermal properties.
• Ion Exchange & Chelating Resins: Serves as a key precursor or functional monomer in the synthesis of resins for water treatment and metal recovery due to its high amine content.
• Paper Wet-Strength Additive: Acts as a cationic polyelectrolyte to enhance the wet strength and dry strength of paper products.
• Textile Finishing Agent: Imparts durable press, wrinkle resistance, and anti-shrinkage properties to fabrics through covalent bonding with cellulose fibers.
• Biomaterial & Drug Delivery: Investigated for use in creating biodegradable hydrogels and polymeric carriers for controlled drug release applications.
• Flocculant & Retention Aid: Used in water clarification processes and in the paper industry to aggregate fine particles and improve retention.
• Adhesive & Sealant Formulation: Enhances the performance of structural adhesives and sealants by providing improved adhesion and cohesion.
