3M hot melt adhesives are 100% solids, thermoplastic resins that become fluid when heated and quickly wet the bonding surface. They cool, harden and reach bond strength in seconds, keeping production flowing by eliminating clamps, fixturing and drying and saving time energy and space. 3M hot melt adhesives are thermoplastic adhesives with low to medium viscosity and long open times. They bond to wide variety of substrates such as wood, plain and coated corrugated, sand cores, foams, many plastics and other lightweight materials. - 3M hot melt adhesive 3792 with 100% solids, thermoplastic resin.
