In most industrial applications, PUR hot melt glue has good merits over the solvent glues as the level of Volatile Organic Compounds emitted from them is high.PUR hot melt glue is a 100% thermoplastic base that requires heated temperature to melt flow the glue into a molten state for bonding and sealing before turning to a solid-state when cooled. Hot melt adhesives have long shelf life and usually can be disposed of without special precautions.
PUR hot melt glues are heated before processing and applied in a molten state. The reactive groups in the hot melt adhesives also have an extremely positive effect on the adhesion spectrum, as the adhesive can additionally form solid chemical bonds with suitable reaction partners on the substrate surfaces.These PUR hot melt adhesives are a successor of traditional thermoplastic hot melt adhesives, mostly based on EVA and Polyolefin polymers. As with traditional hot melt adhesives, initially, cooling results in a purely physical strength build-up, which results in a corresponding initial strength. In the days after chemical cross-linking then takes place through reaction with water molecules which are taken from the glued substrate or air humidity.
