Understanding Hot Melt Applicators

3M Hot Melt Applicators , also referred to as 'glue guns,' are tools used to apply liquefied thermoplastic adhesives and are available in low and high-temperature versions. Low-temperature adhesive applicators operate at approximately 250°F/121°C and are beneficial when bonding heat sensitive materials such as electronics, plastics, and cloth. High-temperature applicators operate at a minimal temperature of approximately 380°F/193°C and can dispense adhesives that produce a stronger bond than low-temperature adhesives.

Melted 3M Hot Melt Adhesive is extruded through the nozzle by either pneumatic pressure, a mechanical trigger mechanism, or with pressure applied directly on the stick. Different nozzles can be used to apply thin, wide strips or narrow, thicker beads. Hot melt adhesive generally sets quickly, ranging from a few seconds to a few minutes, depending on the adhesive formulation.
