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 adhesive 3764 and 3748 bond to a wide variety of substrates such as wood, plain and coated corrugated, fabrics and foams, plastics and other lightweight materials. - 3M hot melt adhesive 3764 is a clear, 100% solids thermoplastic adhesive capable of bonding to many plastics, including polyolefin. Formulated to be flexible at low temperatures, we designed this Hot melt adhesive to deliver exceptional performance for a wide range of applications and industries.
