- 3M™ Scotch-Weld™ Urethane Adhesives 3532 B/A, 3535 B/A and 3549 B/A are
two-component, polyurethane adhesives which cure at room temperature or with
heat to form tough, impact-resistant structural bonds. Their adhesion properties are
identical and they vary only in work life, cure time and color. They provide
excellent adhesion to many primed or painted metal and plastic substrates and are
designed to develop sag resistance approximately 30 seconds after mixing.
- 3M™ Scotch-Weld™ Structural Adhesive Primer EC-3901 is suggested for use on
metal surfaces to achieve maximum resistance to water, humidity and salt spray.
