Description

1,2-Ethanediamine, N,n-Bis(2-Aminoethyl)-, Polymer With Methyloxirane is a specialized polyetheramine polymer derived from ethylenediamine and propylene oxide. This compound is valued for its unique combination of reactive amine end-groups and a flexible polyether backbone, making it a versatile building block and performance additive. It is primarily used by formulators and manufacturers in the polyurethane, epoxy resin, and surfactant industries to modify flexibility, curing characteristics, and surface activity.

Application

• Polyurethane Elastomers & Coatings: Acts as a chain extender and curing agent, imparting improved flexibility, impact resistance, and low-temperature properties to polyurethane systems.
• Epoxy Resin Curing & Modification: Serves as a flexible curing agent for epoxy resins, enhancing toughness and reducing brittleness in adhesives, coatings, and composite materials.
• Surfactants & Demulsifiers: Used as an intermediate in the synthesis of specialty surfactants, emulsifiers, and oilfield demulsification agents.
• Fuel & Lubricant Additives: Functions as a dispersant and detergent precursor in fuel and lubricant formulations to prevent sludge and deposit formation.
• Textile & Leather Auxiliaries: Employed in the production of softening agents, dyeing auxiliaries, and finishing chemicals for textiles and leather.
• Concrete Additives: Can be used as an intermediate for concrete admixtures that improve workability and final strength.
