3M™ Hot Melt Adhesive 3738 is a clear, multipurpose adhesive for effectively bonding wood, lightweight metals and some plastics in furniture, upholstery and woodworking applications.

Open Bond Time Allows for Fit Adjustment and Positioning 3M™ Hot Melt Adhesive 3738 features a 50 second open time that allows for positioning and adjustment on wood, polypropylene, corrugated boxes and lightweight substrates. Its nearly instant bonding property reduces production time for POP assembly, joining, attaching, securing, repairing, potting, panel bonding, wire tacking, bundling, sealing, encapsulating, rigidizing, foam bonding, and packaging. For use with a 3M™ Hot Melt Applicator. Recommended Applications Cabinetry Woodworking Sound damping Furniture manufacturing Upholstery POP displays General industrial Understanding Hot Melt Adhesives Hot melt adhesives, also known as glue sticks, are liquefied thermoplastic adhesives available in both low and high-temperature versions. Low temperature hot melt adhesives are applied at 250ºF/121ºC temperatures, which makes them ideal for bonding electronics, plastics, cloth and other heat sensitive materials. High temperature hot melt adhesives are applied at 380ºF/193ºC and produce a stronger bond than the low temperature hot melts.  Melted adhesive is extruded through a nozzle using a 3M Hot Melt Applicator by either pneumatic pressure, a mechanical trigger mechanism, or with pressure applied directly on the stick. Different nozzles can be used to apply thin, wide strips or narrow, thicker beads. Hot melt adhesive generally sets quickly, ranging from a few seconds to a few minutes, depending on the adhesive formulation.
