Overview
3M™ Scotch-Weld™ Urethane Adhesive EC-3532 B/A is engineered for strong, impact-resistant structural bonding across metals, plastics, composites, and many primed or painted substrates. This two-part adhesive cures at room temperature in 24 hours or faster with heat, providing flexibility for production schedules. Designed to develop sag resistance approximately 30 seconds after mixing, EC-3532 B/A prevents dripping and ensures precise application. With a 5–15 minute worklife, it allows ample time for positioning parts before curing. The adhesive can be applied using spatulas, trowels, or flow equipment, making it versatile for aerospace and industrial applications where reliability and efficiency are critical.
