Hot melt glue or adhesive, is a of thermoplastic glue that is availaible in sticks (11mm, 43mm) to be applied with a standard a hot glue gun.
The glue is tacky and sticky when hot, and cools down in a few seconds to enable a fast bond and further processing. Intercol’s Hot melt adhesives can also be applied by jetting, roller coating, wheel application, dipping, swirl and spraying.
Hot melt adhesives offer several advantages over solvent-based glues and adhesives. Volatile organic compounds (VOC) are eliminated, and the “drying” process is very quick (fast setting speed). Hot melt adhesives have a almoste permanent shelf life and normally can be disposed of without special precautions. You might be carefull with substrates that are sensitive to higher temperatures, and loss of bond adhesive strength at higher temperatures, or even a complete melt of the adhesive. PUR or PU-reactive adhesives will qure after applying and therefore these are almost not temperature dependent. Most PUR hot melts are resistant to chemical attacks and have a high durability due to weathering. hot melt adhesives do not lose thickness (like with vaporizing water or solidus) during solidifying; solvent-based and waterbased adhesives may lose up to 50-70% of layer thickness when dried.
