Used primarily as a curing agent in epoxy resin systems, it enhances flexibility and toughness in the final product. It is also employed in coatings, adhesives, and sealants, where it improves durability and resistance to environmental factors. In the production of elastomers, it acts as a chain extender, contributing to better mechanical properties. Additionally, it finds application in the synthesis of polyurethane foams, where it helps in achieving desired foam characteristics such as density and elasticity. Its compatibility with various polymers makes it versatile in industrial applications.
