What Is a Polyurethane Hot Melt Adhesive?
Polyurethane hot melt adhesive is made from solid-state polyurethane resin that melts when heated and solidifies upon cooling to form a bond. This adhesive is primarily utilized for bonding materials like plastic, fabric, and paper, consisting of polyurethane resin and various additives. When the solid adhesive is heated, it becomes a viscous liquid that, upon cooling, reverts to a solid state, creating a durable adhesive film.
Its use spans a wide range of applications, including bonding plastic items, fabric repairs, and paper product assemblies. The defining features of polyurethane hot melt adhesive are its quick drying time, resistance to water and heat, and user-friendly application process. These properties make it highly adaptable for various scenarios and materials, offering an efficient and reliable bonding solution.
