1.1 ,This specification covers two-part adhesives for bonding foam core sandwich panels. The adhesive may be used for new production or depot maintenance. The adhesive should be suitable for forming bonds that can withstand long-term exposure to temperatures from ,−,55 to 93°,C (−,67 to 200°,F) and also withstand combinations of stress, temperature, and humidity expected to be encountered in service. The adhesives shall be used for bonding aluminum alloy facing to foam core, inserts, internal aluminum framing members, and other components of a foam cored sandwich panel.
