When used with compatible glue guns, hot melt glue sticks bond materials almost immediately after application. Hot melt adhesives are made of solid, thermoplastic resin, which takes on a fluid, molten state when heated, but cools and hardens to reach bond strength within minutes. The quick setting time reduces the need for clamps and allows work to continue immediately after gluing. In comparison with solvent-based adhesives, hot glue sticks offer a longer shelf life, easier disposal, and short drying or curing steps. Use in packing and assembly applications.
