Hot melt adhesives are 100% solids that do not contain solvents or water. Hot melt adhesives melt to viscous liquids at higher temperatures and solidify again when cooled down. This purely physical effect of thermoplastic hot melt adhesives can be combined with a second curing process. These so-called reactive hot melt adhesives additionally cure with the humidity present in the environment to no longer smeltable thermosets.
