Aggressive Hot Tack Rapidly Achieves Handling Strength
3M™ Hot Melt Adhesive 3762 is 100% solids, thermoplastic resin formulated to grab and seal quickly to meet the demands of high-volume production settings such as packing, woodworking and assembly. These features increase the speed of carton closures and provide adhesion to wood, paperboard, corrugated and other fibrous substrates. It provides strong shear strength, which means your packages stay sealed and components stay bonded under most conditions. A 25 second open time, along a 1/8" bead, is sufficient for positioning and adjusting for fit and supports high-tempo productivity for packaging, woodworking, and applications that involve fibrous materials. The low viscosity prevents stringing even at fast production speeds. Recommended application temperature range: 350-385°F (177-196°C).
Recommended Applications
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.
