Understanding 3M™ Scotch-Weld™ Polyurethane Reactive (PUR) Adhesives3M™ Scotch-Weld™ PUR Adhesives are one-component, moisture-curing urethane adhesives that are applied warm to create dramatically strong bonds to a variety of substrates such as wood , fiber reinforced plastic (FRP) and many other plastics to themselves, to metal and to glass. Fast-acting strength begins to build as the adhesives cool for rapid, convenient application with minimal downtime from clamping or fixturing. These adhesives can be extruded from hand held or bench mounted 3M™ Scotch-Weld™ PUR Adhesive Applicators. PURs offer attractive options: from woodworkers searching for thin bond lines and replacing unsightly mechanical fasteners, to plastic, glass and metal materials assembly in automotive, electronics, general assembly and many other industries.
