Preheating Cartridges Saves Valuable Time Keeping preheated cartridges available is particularly important in high volume usage areas where a 45 minute wait for heating cartridges can disrupt workflow and reduce employee productivity. Featuring 170ºF and 250ºF temperature options, the 3M™ Scotch-Weld™ PUR Easy 250 Preheater is an important tool when working with the 3M™ Scotch-Weld™ Polyurethane Reactive (PUR) Easy 250 Applicator. Recommended Applications Heats and maintains 3M™ Scotch-Weld™ PUR cartridges Understanding 3M™ Scotch-Weld™ Polyurethane Reactive (PUR) Adhesives 3M™ 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.
