Used as a curing agent and crosslinking agent in epoxy and polyurethane systems, especially in the production of high-performance elastomers, coatings, and composites. It enhances thermal stability, mechanical strength, and chemical resistance of the final product. Commonly applied in the manufacturing of industrial coatings, adhesives, sealants, and electronic encapsulants where durability and resistance to harsh environments are required. Also utilized in specialty polymers for aerospace and automotive industries due to its ability to improve chemical and heat resistance.
