Hot 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.

Model Number 3750LM—3750LM is FDA compliant 21 CFR 175.105 for use in food packaging. It is a low-temperature formulation, which works well on delicate or heat-sensitive materials.

Model Number 3762—3762 are high-tack adhesives; they bond quickly with light pressure.

Model Number 3762LM—3762LM are low-temperature formulations, which work well on delicate or heat-sensitive materials. 3762LM are high-tack adhesives; they bond quickly with light pressure.

Model Number 3792LM—3792LM are low-temperature formulations, which work well on delicate or heat-sensitive materials.
