SAE AMS3689B

This specification covers a foaming-type, heat-curing, resin-base adhesive in the form of paste or sheet. Primarily for use in splicing aluminum alloy or nonmetallic honeycomb core and for providing a shear tie between core edges and inserts or edge members in honeycomb assemblies for use over the range -54 to +177C (-65 to +350F). It is useful for filling gaps between core faces which are inserted into channels or similar areas where bonding pressure cannot be obtained.
