3M™ Scotch-Weld™ Hot Melt Adhesive 3776LM is a hot melt adhesive used for bonding light gauge metal, primed, and unprimed metal to various substrates and to themselves. It is a 100% solids, thermoplastic adhesive that dispenses at a low temperature (265°F/129°C) for general purpose industrial assembly.
3M™ Scotch-Weld™ Hot Melt Adhesive 3776LM is a low temperature dispensing hot melt adhesive. This product hardens and reaches bond strength in seconds, providing quick assembly and fast results. It can be used for bonding light gauge metal as well as primed and unprimed metal to various substrates and to themselves. 3M™ Scotch-Weld™ Hot Melt Adhesive 3776LM can also be used with wood, paper, and some plastics. For use with a 3M™ Scotch-Weld™ Hot Melt Applicator. Hot melt adhesives, also known as glue sticks, are liquefied thermoplastic adhesives available in both low and high-temperature versions. Low temperature hot melt adhesives are applied at 250°F / 121°C temperatures, which makes them ideal for bonding electronics, plastics, cloth and other heat sensitive materials. High temperature hot melt adhesives are applied at 380°F / 193°C and produce a stronger bond than the low temperature hot melts.Melted adhesive is extruded through a nozzle using a 3M™ Scotch-Weld™ Hot Melt Applicator 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.
