Description
FM 377 film adhesive is a modified epoxy that cures at 177 °C (350 °F) and is designed for continuous service at that temperature. The manufacturer quotes structural performance from -55 °C to 177 °C, combining high peel strength with high-temperature shear. Shop life is 30 days at 24 °C, and the unsupported grade reticulates easily onto honeycomb or perforated metal.
The manufacturer describes it for bonding metallic, non-metallic and sandwich structures, co-cure and secondary bonding of composites, and nacelle bonding on perforated skins.
