About Structural Adhesives

When heated, these glue sticks melt and quickly begin to harden. Use them to seal packaging and form other low- to medium-strength bonds. 3M glue sticks work only with 3M glue guns.

Adhesives that take longer to harden are suited for applications that require some repositioning, because the longer open times allow for more adjustment. For high-volume applications, adhesives with a lower viscosity flow faster than other hot-melt adhesives.

3750LM is FDA compliant 21 CFR 175.105 for use in food packaging.

3750LM, 3762LM, and 3792LM are low-temperature formulations, which work well on delicate or heat-sensitive materials.

3762 and 3762LM are high-tack adhesives; they bond quickly with light pressure.

Cordless Hot-Melt Glue Guns

Don't be tethered by a cord—take these guns where they're needed.

Continuous duty guns use electric or battery power to dispense glue. Use a battery adapter (sold separately) with your DeWalt, Makita, or Milwaukee batteries. Intermittent duty guns dispense glue for up to 3 minutes per charge.
