Maximum Adhesion With PUR Hot Melt Adhesives For Maximum Results In 2022

With moisture cured, reactive hot melt adhesives based on polyurethane (PUR), you can rely on maximum adhesion for interior and exterior use. When the adhesive cools down, it builds up its green strength through a physical hardening process, triggered by water molecules (from the substrate or the air). PUR reactive hot melt adhesives provide a stronger bond with a superior resistance against moisture, heat and chemicals.Our PUR hot melt adhesives impress customers with their very good water and temperature resistance and are a byword for perfect adhesion wherever it is needed e.g. for hard-wearing plastic furniture surfaces, wall and ceiling panels as well as window components for the interior and exterior,PUR hot melt adhesives are heated before processing and applied in molten state.

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.Reactive hot melt adhesives are heated before processing and applied in a molten state. These PUR hot melt adhesives are a successor of traditional thermoplastic hot melt adhesives, mostly based on EVA and Polyolefin polymers.
