3M™ Scotch-Weld™ Core Splice Adhesive EC-3500 B/A is a two-part void filling material designed for filling mismatched areas, core splicing and reinforcing honeycomb core. This low density formula features a long work life and high shear strength, even at increased temperatures.
3M™ Scotch-Weld™ Core Splice Adhesive EC-3500 B/A provides a solution to core splicing, filling mismatched areas and reinforcing honeycomb core. It is a two-part, modified epoxy adhesive paste with a low density and low volatile loss during cure. This ensures the adhesive retains a consistent and thorough bond even after curing. This adhesive provides high performance over a broad range of temperatures ranging from -67°F-350°F (-55°C-177°C). 3M™ Scotch-Weld™ Core Splice Adhesive EC-3500 B/A features good shear and compression strength to ensure bonded substrates continue to perform as expected, even under stress and vibration. Even at high temperatures, the adhesive retains good core shear strength.
