Adipic acid dihydrazide is widely used as a crosslinking agent in the production of polymers and resins. It is particularly effective in enhancing the thermal and mechanical properties of materials such as coatings, adhesives, and elastomers. In the paint and coating industry, it improves the durability and resistance of finishes to chemicals and weathering. Additionally, it serves as a key component in the synthesis of polyurethane foams, where it contributes to better foam stability and strength. Its ability to form strong covalent bonds makes it valuable in modifying cellulose-based materials, improving their water resistance and dimensional stability. In the textile industry, it is used to treat fabrics, providing enhanced wrinkle resistance and durability.
