A hot melt adhesive is a thermoplastic material, solid at room temperature, which is applied in its molten form and will adhere to a surface when cooled.

The wax is used as an additive in hot melt adhesive composition, which is used in bonding articles such as those made from fibrous cellulosic materials, plastic, wood, metal, etc.


A Brief History of hot melt

When some natural materials fell on rocks heated by the sun, they softened and became sticky, and later hardened in the cool of the night. Observers made use of these natural phase-change materials as they chanced upon them. When lightning started fires some materials melted and then cooled in interesting shapes. Observers, using the fires to harden their sharpened stick weapons, put out the fires by rubbing their sticks on the ground, and some contacted and melted resins, which when cooled, again hardened. Thus was born the technology we now call hot-melt adhesives.
