ARALDITE® MY 720

ARALDITE® MY 720 is a tetrafunctional epoxy resin suitable for high-performance composite applications. Cured at 120°C (250°F) to 175°C (350°F), Araldite® MY 720 provides outstanding performance characteristics at elevated temperatures. When post-cured at 200°C (400°F), the system exhibits properties exceeding 220°C (430°F). Araldite® MY 720 systems can display Tgs.
