3M Scotch-Weld™ 3532 B/A Two-Part Structural Adhesive
Categories:	Polymer; Adhesive
Material Notes:	3M™ Scotch-Weld™ Urethane Adhesives 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 second after mixing. Information provided by 3M
