  • Applications

    Polymer aziridine with methyloxirane and oxirane units is primarily used as a crosslinking agent and curing agent for epoxy resins in industrial coatings, adhesives, and plastics, improving network strength, thermal resistance, and chemical durability of the polymer matrix. It is also employed in electronics encapsulation/potting formulations to enhance dielectric performance and mechanical integrity of epoxy systems, and can serve as a component in composite resins or functional polymer formulations.
