What to Know About Hot Melt Adhesives
Hot melts are 100% solids thermoplastic resins. These adhesives are engineered to re-melt after bonding if exposed to high enough temperatures. The advantages of hot melt adhesives is that, unlike mechanical fasteners and sealing tapes, they are virtually invisible between surfaces.

Our hot melt adhesives liquefy when heated, quickly fill gaps and wet the bonding surface. When they are applied to a surface, they cool, harden and reach their bond strength within seconds. Due to their quick work-life, you can move assemblies immediately upon application which eliminates the need for clamps, fixturing or additional drying time and energy.

Exceed Your Expectations
Discover the advantages of 3M™ Hot Melt Adhesive 3748, formulated to be flexible and ready to meet your application requirements. We engineered this hot melt glue to excel in electrical applications and withstand a variety of different environments through its excellent low temperature thermal shock properties and heat resistance. Our Hot Melt Adhesive 3748 is a quick solution, ready to exceed your expectations.
