• For use with 3M Polygun TC Applicator. 5/8″ diameter, 8″ long
• Approx 15 sticks/lb.
• 100% solid solvent free thermoplastic resins
• Assemblies can be moved immediately
• 45 second open time (bonding range)

Product Description
3M Scotch-Weld Hot Melt Adhesives liquify when heated and quickly fill gaps and wet the bonding surface. Applied to only one surface, they cool, harden, and reach bond strength in seconds. You can move assemblies immediately and eliminate clamps, fixturing, and drying time. Unlike mechanical fasteners and sealing tapes, hot melt adhesive is virtually invisible between the mating surfaces.
Letters usually refer to the type of gun used for the particular stick
3747: A general purpose hot melt adhesive for bonding most plastics, wood and light gauge metal. It offers good heat resistance, good impact resistance, flexibility and has a high delivery rate with a moderate bonding range.
3738: Used to manually seal corrugated cartons, cases and packaging
3792LM: (LM = Low Melt); a clear, general purpose hot melt adhesive for product assembly. It features a long bonding range, good heat resistance, and good adhesion to many plastics and wood; similar in performance to Scotch-Weld Hot Melt Adhesive 3792.
Sold in 11 lb. cases
