We developed 3M™ Scotch-Weld™ Urethane Adhesive EC-3532 B/A as a fast acting, two-part urethane adhesive which cures at room temperature or with heat to form tough, impact-resistant structural bonds. Our adhesive offers strong adhesion on metals, plastics, composites and many primed or painted metal and plastic substrates. It also becomes non-sag approximately 30 seconds after mixing.
