We formulated 3M™ 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 melt 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 hot melt adhesives 3750 are heat applied, 100% solids adhesives. They are fast setting thermoplastic adhesives with good hot tack and low to medium viscosity. 3M hot melt adhesives bond to a wide variety of substrates such as corrugated, beadboard, repacking chipboard, recouperage, wood and many other lightweight materials.
