FM®450-1 film adhesive is a next generation high performance BMI adhesive for bonding both composite and metallic structures. This new adhesive provides a unique combination of high Tg, toughness and high temperature shear properties. FM®450-1 has excellent resistance to pre-bond and post-bond humidity and has good retention of properties up to 450°F (232°C). FM®450-1 film adhesive delivers excellent tack and drape and has a minimum shop life of 30 days at 75°F (24°C).
FM®450-1 is compatible with Cytec’s industry leading CYCOM®5250-4 BMI prepreg. FM®450-1 film adhesive can be cured at 375°F (191°C) followed by a freestanding post cure at 440°F (227°C) or by following the BMI prepreg cure cycle. The unsupported film adhesive can be easily reticulated onto perforated skins or honeycomb for acoustic applications. Typical applications for FM®450-1 include co-cure, co-bond or secondary bonding of both metallic and composite applications.
