Highlights
  • Aggressive hot tack rapidly achieves handling strength for packaging and other applications
  • Low viscosity provides high flow rate to support fast-paced production
  • Open time allows for positioning and fit adjustment
  • Both hot melt and low melt versions for bonding a variety of materials
  • Bonds corrugated or paperboard cartons, wood, particle board, chipboard and cushioning foams

We formulated 3M™ Scotch-Weld™ Hot Melt Adhesive 3750 to grab and seal quickly, and meet the demands of high-volume production settings such as packing, woodworking, and assembly. When heated to its specified melting point, this adhesive achieves a low viscosity/ high-flow rate and an aggressive hot tack that bonds to handling strength in seconds to help maintain high-tempo productivity.

3M™ Scotch-Weld™ Hot Melt Adhesive 3750 provides strong shear strength and low peel strength, which means your packages stay sealed and components stay bonded under most conditions. Its 30 - 40 second open time, along a 1/8 in (0.32 cm) bead, is sufficient for positioning and adjusting for fit and supports high-tempo productivity for packaging, woodworking, and applications that involve fibrous materials. We manufacture 3M™ Scotch-Weld™ Hot Melt Adhesive 3750 using 100% solids, thermoplastic resin for use with 3M™ Scotch-Weld™ Hot Melt Applicators. As a low-volatile-organic (VOC) compound, this adhesive produces minimal odour when heated and helps support a comfortable work environment. Hot melt adhesives/hot-glue sticks have a relatively hot melting point that ranges between approximately 250-380°F/121-196°C, depending on the formulation, and are applied with hot-melt applicators, commonly referred to as hot-glue guns. Hot-melt glues provide a nearly instant bond between many plastics, paper and wood, but when the bond is reheated, some varieties will soften, allowing the bonded surfaces to be separated. The quick-stick nature of hot-melt adhesives speeds up operations in packaging and production.
