Understanding Hot Melt Adhesives
Applied with 3M Adhesive Applicators, hot melt adhesives extrude as liquefied thermoplastic to fill gaps and wet entire bonding surfaces before setting. As a result, they often exceed 100 psi shear strength for quick, convenient strength. Hot melt adhesives are used for bonding a wide variety of materials ranging from wood to corrugated cardboard, heat-sensitive foam, plastics and metals. Unlike mechanical fasteners or sealing tapes, hot melt adhesives are virtually invisible between mating surfaces. These 100% solids thermoplastic resins are available in a variety of strengths, temperatures and pen time/bonding ranges to meet your specific application demands.
