PUR Hot Melt Glue, scientifically known as Polyurethane Reactive (PUR) adhesive, is a single-component, 100% solid material based on isocyanate-terminated urethane prepolymer. Renowned for its robust bonding strength, it offers exceptional resistance to extreme temperatures, moisture, abrasion, chemical corrosion, and aging—making it ideal for bonding plastics and metals in industries like electronics, automotive, and aerospace. When deployed with a PUR Hot Melt Glue Laminating Machine, the melted adhesive is uniformly applied via dot transfer technology, enabling precise control over coating thickness and the tactile properties of laminated products.
