This specification covers two-part adhesives for bonding aluminum alloy facing to foam core, inserts, edge attachments, and other components of a Type II foam cored sandwich panels. The adhesive should be suitable for forming bonds that can withstand long-term exposure at specified temperatures, and different combinations of stress, temperature, and humidity expected to be encountered in service. The adhesive may be used for new production or depot maintenance. The adhesive shall be a two-part thermosetting epoxy paste containing no asbestos and, when tested, shall meet the following physical and mechanical property requirements: curing time, temperature, and pressure; mix ratio; storage life; adhesive life; room-, low-, and high-temperature shear; hot humidity exposure shear; and room-temperature salt spray exposure shear.

|Significance and Use|
5.1 This specification is intended to provide information on the properties of adhesives, and the test methods required to evaluate adhesives to be used in the production bonding of aluminum alloys to foam core materials for the manufacture of tactical shelters.
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.
1.2 The values stated in SI units are to be regarded as the standard where only SI units are given or where SI units are given first followed by inch-pound units; where inch-pound units are given first followed by SI units, the inch-pound units are to be regarded as the standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
