''Hot adhesives'', also known as ''hot melt adhesives'', are [[thermoplastic]]s applied in molten form (in the 65–180&nbsp;°C range) which solidify on cooling to form strong bonds between a wide range of materials. [[Ethylene-vinyl acetate]]-based hot-melts are particularly popular for crafts because of their ease of use and the wide range of common materials they can join. A glue gun (shown at right) is one method of applying hot adhesives. The glue gun melts the solid adhesive, then allows the liquid to pass through its barrel onto the material, where it solidifies.

Thermoplastic glue may have been invented around 1940 by [[Procter & Gamble]] as a solution to the problem that water-based adhesives, commonly used in packaging at that time, failed in humid climates, causing packages to open.  However, water-based adhesives are still of strong interest as they typically do not contain volatile solvents.<ref>{{Cite journal |last1=Bhakare |first1=Madhuri A. |last2=Lokhande |first2=Kshama D. |last3=Bondarde |first3=Mahesh P. |last4=Dhumal |first4=Pratik S. |last5=Some |first5=Surajit |date=2023-02-15 |title=Dual functions of bioinspired, water-based, reusable composite as a highly efficient flame retardant and strong adhesive |url=https://www.sciencedirect.com/science/article/pii/S1385894722059010 |journal=Chemical Engineering Journal |volume=454 |pages=140421 |doi=10.1016/j.cej.2022.140421 |bibcode=2023ChEnJ.45440421B |issn=1385-8947}}</ref>
