Problems solved by technology

[0002] Pressure-sensitive adhesives and their products have developed rapidly in the past two decades, and their applications have spread throughout various fields of the national economy and have entered thousands of households. However, in the application of basic research and technology development of pressure-sensitive adhesive products, There is still a big gap between China and developed countries. Some high-performance pressure-sensitive adhesive products still rely on imports from developed countries. Pressure-sensitive adhesives that can be used in the waterproof industry are only 0.2mm to 0.4mm thick in products, so the adhesive is required It must have a strong cohesion to achieve the required bonding strength. The hot melt pressure-sensitive adhesives currently prepared have problems such as insufficient adhesion to non-polar materials and other specific applications.
