Polyurethane adhesives are used in the wood industry, automobile decoration, packaging, wall material bonding and other industries. The reason why it has been so widely used is that it has excellent performance. Today, the editor has made the performance of polyurethane adhesives. Description:
1. As the polyurethane adhesive contains isocyanate groups and urethane groups in the molecular chain, the polyurethane adhesive exhibits a high degree of activity and polarity. It has extremely high adhesion to a variety of materials, not only for bonding porous materials, but also for bonding materials with smooth surfaces.
2. At the same time, it has a flexible molecular chain, so it has good vibration resistance and abrasion resistance, and it can be used for bonding between porous materials and different materials such as smooth surface materials.
3. In addition, an important feature of polyurethane adhesives is low temperature resistance and good ultra-low temperature performance.
The above is the description of its excellent performance. In short, polyurethane adhesives have strong toughness, elasticity and fatigue resistance, strong adhesion and long bonding time. Because of this, it will be widely used and recognized.
