About Hot Melt Adhesives
Hot melts (hot glue sticks) 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.
Hot Melt Adhesion for High Performance
3M™ Hot Melt Adhesive 3779 eliminates the need for clamps, fixturing or additional drying time. This high performance adhesive quickly fills gaps and wets the bonding surface. When applied to a surface, this adhesive cools, hardens and reaches its bond strength within seconds. Improve productivity, lower costs, minimize waste and keep production flowing with our 3M™ Hot Melt Adhesives.
