Detail:
PUR hot melt adhesive is a one-component solvent-free 100% solid active polyurethane prepolymer. It becomes fluid after heating and melting. It is easy to use. The moisture reacts with it, cross-links to form an inert structure, and generates a high-molecular polymer with high cohesion, which significantly improves the bonding strength, high temperature resistance, and low temperature resistance. Due to its high reactivity, it has a very wide range of applications.
Reactive polyurethane hot melt adhesive uses polyurethane as the base material, so it has the general characteristics of polyurethane. Reactive hot melt adhesive has strong adhesion to the surface of many difficult-to-stick materials, and has a wide range of applications. It can not only bond porous materials , such as: foam plastics, ceramics, wood, fabrics, etc., and can bond materials with smooth surfaces, such as: stainless steel, aluminum, metal foil, leather and rubber. At the same time, it is also very good for the bonding between porous materials and smooth surface materials, and can achieve a relatively high cohesive strength.
