About Structural Adhesives

The polyurethane glue in these cartridges has nearly twice the shear strength of other hot-melt adhesives.

Hot-Melt Glue Sticks

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.

3762 is a high-tack adhesive; it bonds quickly with light pressure.

3789 joins hard-to-bond plastics and resists fuel and oil.

LM denotes low-temperature formulations. These work well on delicate or heat-sensitive materials.
