3M™ Hot Melt Adhesive 3748 is a tough, flexible hot melt adhesive with exceptional low temperature thermal shock properties that is able to provide optimal adhesion in fluctuating temperatures. As a 100% solids thermoplastic resin, this hot melt adhesive offers excellent durability for a wide variety of applications.

Provides High Temperature Stability 175ºF / 79ºC for a Durable Bond 3M™ Hot Melt Adhesive 3748 provides good resistance to heat, impact, fuel and oil. It is manufactured using 100% solids, thermoplastic resin for use with a 3M™ Hot Melt Applicator. This adhesive provides high temperature stability 175°F / 79°C with a 25-second open time that is sufficient for fit positioning and adjusting. 3M™ Hot Melt Adhesive 3748  will bond wood, polypropylene, electronics, vinyl and lightweight substrates on furniture, automotive interiors, outdoor applications, small appliances and general product assembly. Recommended Applications Transportation interiors Seating attachment General product assembly 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.
