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.

Flame-Retardant Epoxy Structural Adhesives

These self-extinguishing epoxies meet UL 94 V-0 for flame retardance. The strongest and most weather- and chemical-resistant structural adhesives, epoxies work especially well on metals.
The size listed is the combined total of the two parts. Use a dispensing gun and mixer nozzle to simultaneously mix and dispense adhesives.
Certificates with a traceable lot number and product shelf life are available for these products. Download certificates from ORDER HISTORY after your order ships.
