3M™ Hot Melt Adhesive 3738PG, Tan, 1 in x 3 in (2.54 cm x 7.62 cm), 22 lb (9.97 kg), Case

3M™ Hot Melt Adhesive 3738 is a tan-colored, general-purpose thermoplastic adhesive that delivers high delivery rates and a long bonding range for versatile industrial applications. This adhesive provides fast, durable bonds to foundry sand cores, wood, corrugated materials, selected plastics, and chipboard. Dispensing at temperatures up to 400 °F with a viscosity of 2,875 CPS at 375 °F, it offers excellent performance across multiple substrates with a 50-second open time for precise positioning.

3M™ Scotch-Weld™ Hot Melt Adhesive 3738-B features a 50 second open time that allows for positioning and adjustment on wood, polypropylene, corrugated boxes, and lightweight substrates. Its nearly instant bonding property reduces production time for POP assembly, joining, attaching, securing, repairing, potting, panel bonding, wire tacking, bundling, sealing, encapsulating, rigidizing, foam bonding, and packaging. 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, 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 adhesives are 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.
