Overview
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 sec after mixing. 3M™ Scotch-Weld™ urethane adhesives EC 3532 B/A creates strong impact-resistant bonds and is engineered to be sag-resistant approximately 30 sec after mixing so the adhesive doesn't run, drip or migrate. Its 5 to 15 min work life allows ample time for handling, accurate application and positioning of parts. EC 3532 B/A forms a fast, secure bond between parts for desired results. To help keep your processes moving forward, 3M™ Scotch-Weld™ urethane adhesive EC 3532 B/A cures in 24 hr at room temperature or sooner with heat. This option gives you control over the speed in which the bond reaches the shear strength required. And to meet various application methods and other needs, Scotch-Weld™ EC 3532 B/A can be applied using a spatula, trowel or flow equipment.
Features & Benefits
Eliminating the need to damage surfaces (i.e. drilling holes)
Joining dissimilar materials and works well with many surfaces
Producing aesthetically pleasing results as refinishing steps are not required
Good environmental and chemical-resistance
Delivers excellent temperature and solvent-resistance
Does not need access to air or moisture to dry and therefore has an unlimited depth of cure
Excellent adhesion to many primed or painted metal and plastic substrates minimizes prep
