EPOCAST® 1652 A/B

EPOCAST® 1652-A/B is a low-density system with good elevated temperature performance after a room-temperature cure. The epoxy syntactic is suitable for core filling metal skins, adding stiffness and strength to fabricated parts such as helicopter rotor blades, core splicing, and strengthening radii and corners of reinforced plastic structures. EPOCAST® 1652-A/B is qualified to Grumman GM 4006, Gulfstream GMS 4005, and Sikorsky 9587, Type 2.
