Any polymer-based glue that is applied in a molten state is known as hot melt. An industrial glue gun, which works by either trigger action or finger pressure, is typically used to apply the adhesive. Due to its flexibility, hot melt is utilised in a range of applications, including as packaging, bookbinding, carton-making, graphic arts, tapes and labels, product assembly, and the automobile sector. For a variety of reasons, hot melt is enticing. It is, for one thing, quick-acting. In reality, depending on the demands of the task, the time to cure, or set, can be varied. Hot melt is both ecologically beneficial and safe to use. Hot melt may be used to fill gaps as well as bonding tough surfaces. It's also simple.
Hot melt adhesives have surpassed solvent-based adhesives in popularity. Solvent-based adhesives are made up of a number of different chemicals that have been dissolved in a solvent. The substance adheres after the solvent evaporates. Many of the issues with solvent-based glues are avoided with hot melt, which is polymer-based. Hot Melt Adhesives are quicker, more cost-effective, and more sticky than solvent-based adhesives, and they create far less volatile organic compounds. Hot melt may take a variety of shapes according to its chemical makeup. Glue sticks, pellets, sacks, cakes, drums, bricks, slats, and pillows are all examples. Hot melt can also be applied via nozzles, extrusion, melt blowing, spiral spraying, screen printing, and slot die coating, among other methods.
