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. The 8" long glue sticks require a converter (sold separately) to use with a 3M TC or LT gun.
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.
3789 joins hard-to-bond plastics and resists fuel and oil.

Hot-Melt Potting Compounds
Encase electronic assemblies in a layer of material for protection from dust, moisture, chemicals, mechanical shock, and vibration. Hot-melt potting compounds have excellent flexibility, good chemical and moisture resistance, and withstand a range of temperatures. They provide good electrical insulation. Use 3M glue guns (sold separately) to dispense.
8" long sticks require a converter (sold separately) for use with the TC gun.
