Product Introduction
3M™ Scotch-Weld™ Structural Adhesive EC-1648 B/A is a two-part adhesive that cures at room temperature (75°F / 24°C) within 24 to 48 hours to form a strong, durable bond. It is specifically designed for bonding polyester and metal panels to themselves and to each other, offering good shear, peel, and impact resistance. This adhesive provides increased temperature resistance compared to similar adhesives like 3M™ Scotch-Weld™ Epoxy Adhesive EC-1838 B/A. Formulated as a non-sag paste, it will not drip, run, or migrate on vertical or overhead surfaces. With a 60-minute work life for precise positioning, it can be applied manually or with automated equipment, making it an ideal replacement for mechanical fasteners in structural applications.
