Description
3M™ Scotch-Weld™ EC-3532 B/A Urethane Adhesive is a two-component, room-temperature-curing polyurethane adhesive designed to form tough, impact-resistant structural bonds. It provides strong adhesion to metals, plastics, composites, and many primed or painted substrates, while its formulation develops sag resistance approximately 30 seconds after mixing, making it suitable for vertical and overhead applications. With a 5–15 minute work life and approximately 24-hour room-temperature cure, EC-3532 B/A provides a practical balance between working time and fast bond development. It can be applied using a spatula, trowel, flow equipment, or suitable two-part metering and mixing systems. 3M lists EC-3532 B/A among its aerospace adhesive products and documents its use for demanding structural bonding applications.
