Do you mean "hot melt adhesive"? All adhesives must be able to flow on to and "wet-out" whatever they stick to. Some adhesives are dispersed in water (Elmer's glue), and some use a solvent (Testor's model glue) to give them the ability to flow. Once they wet-out the substrate, the solvent dries, and the bond is formed. Hot melt adhesives use no solvent to help them flow. Instead, they use heat. Hot melt adhesives are solid materials at room temperature that melt when heated. They are applied while molten and the bond is formed when they cool and solidify. A big advantage that hot melt adhesives have over those that use a solvent is that cooling to form a bond is much faster than drying to form a bond and they set up more rapidly. This makes them useful for high speed bonding applications such as making diapers, gluing cereal boxes, putting labels on bottles, etc. Most hot melts are blends of plastic polymers like polyethylene and EVA, resins, and waxes. Some, like the ones used to make Duct Tape and packaging tape, are blends of rubber and resin.

A molten compound is a compound that has been melted down into a liquid. In chemistry, ionic compounds (metal to non-metal) can be melted so that they conduct electricity. This is used in electrolysis.

When some substance, such as granite, or iron or glass, which is normally in a solid phase at room temperature, is heated to the point that it melts, it is then described as molten. The difference between melted and molten is that melting is often a process of dissolving, as when sugar melts in water. Whereas, a molten substance melts only because of heat, it has not dissolved.
