The hot-melts - made of and applications


The Glue Factory | Hot Melts 101: Presented by SWA. Co.

Hot-melt adhesives (also known as hot glues) are generally 100% solid formulations based on thermoplastic polymers (no water or solvents are involved). Hot melts are sold at ambient temperature and are ‘activated’ in the melt stage beyond their softening point, which is usually between 80 and 120 degrees

Once melted (in a hot melt tank), the adhesive can then be applied onto a substrate in its liquified or molten state. The hot melt wets the substrate, penetrating the surface (and any cavities), and then it solidifies, ensuring cohesion. This setting/cooling process takes very little time. Glues that cool and remain tacky are known as pressure sensitive adhesives (PSA) – these we will cover in depth another time.

How do hot-melts work?

Hot melt is the name given to any polymer-based glue that is applied in a molten state. The application of the adhesive is usually by which works through either trigger action (i.e. EVA or PO hot melts upon heating, PUR hot melts moisture-cured) or finger pressure (the PSA hot melts at ambient temperature)

Hot melt is used in a variety of settings due to its versatility, such as:

  • Woodworking (i.e. edge-banding, profile wrapping, lamination)

  • Bookbinding (i.e. offset and printed paper, as spine and side glue)

  • Packaging (i.e. carton-closure, carrier and hand bags, straw attachment),

  • Tapes and labels (i.e. art and kraft-paper, aluminum foil, glass-fiber, and foam)

  • Hygiene (i.e. Feminine and baby diapers as construction, elastic attachment and positioning)

  • Air and oil filtrations (i.e. pleating and frame lamination)

  • Glue Sticks (i.e. DIY work-shop, toys, electronics)
