3M™ Scotch-Weld™ Hot Melt Bonding Systems
3M™ Scotch-Weld™ Hot Melt Bonding Systems
We designed the 3M™ Hot Melt Applicator LT as a lightweight, industrial grade applicator that dispenses liquefied adhesive to meet your needs whenever two surfaces require a strong clean bond. Our low temperature, lightweight applicator uses electric heat to melt and thumb pressure to drive the low-melt adhesive smoothly and evenly to keep various production processes moving.
  • Low operating temperature provides adhesive for heat sensitive parts
  • Balanced design and comfortable grip provide operator control
  • Thumb feed supplies even pressure without touching the glue stick
  • Balanced design for easy, controlled application
  • Top mounted bracket allows applicator to hang in proper position when not in use

How it Works

An operating temperature of 265°F/ 129°C is automatically maintained by a fixed thermostat on the heat block using 120V AC. Designed to be a simple, reliable tool for dispensing low-melt adhesive sticks, this applicator is a great solution for assembling joining, attaching, securing, repairing, panel bonding, and structural bonding. The applicator will utilize 3M™ Scotch-Weld™ low-melt 5/8 inch x 2 inch sticks and bond a wide variety of materials and is an indispensible asset for dozens of applications. The applicator comes with a 0.093" tip that meets a wide variety of needs. It is self-contained and features a comfortable hand-held design for an easily controlled and precise means of manual adhesive application. This applicator is designed exclusively for low-melt-formula adhesive sticks.

What is Hot Melt?
Hot-melt adhesive applicators, commonly called "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.  The applicator creates a flow of adhesive when a solidified adhesive stick is fed into the heat chamber, where it is melted using a fixed-temperature heating element. The molten adhesive is then extruded through a nozzle by either pneumatic pressure, a mechanical trigger mechanism, or with pressure applied directly on the stick. Nozzles can be changed to dispense adhesive in a manner that meets various requirements; from a thin, wide strip for carton sealing, to a narrow, thicker bead for bonding wood, composites, or metal. Nozzles are typically metal and become extremely hot during use, which can quickly burn skin. Once dispensed from the applicator, the adhesive generally sets quickly, in most cases just a few seconds. Hot-melt applicators are widely used in industry, crafts, home, and work with materials ranging from paper and lace to wood and some metals.
