3M Scotch-Weld Advanced Liquid Shim EC-7272 B/A

A two-part epoxy that functions as both a structural adhesive and an advanced liquid shim, curing at room temperature with high compressive strength and toughness over a wide temperature range. It fills gaps (roughly up to 2.5-3 mm) in composite and metallic assemblies to restore alignment and carry load without solid/hard shims, reaching drilling strength in about 4-5 hours. Widely used for rib-to-skin and other load-bearing aero-structure joints to reduce cycle time.
