Polyurethane is generally used in various forms such as coatings, adhesives and fillers for textiles, leather, plastics, wood, concrete, glass and metal materials. There is also growing industrial or commercial interest in polyurethanes, which are characterized by their flexibility, durability, various physical characteristics. Nowadays, high mechanical properties, and slip resistance are often required depending on the application, and in order to improve such properties. There are types and contents of polyols, isocyanates, and curing agents. Many research results on improving the flexibility and wear resistance of polyurethane using siloxane compounds have been published. We have increased the pre-polymer molecular weight of the 2K-polyurethane to improve weathering. Furthermore, the synthesis and characteristic evaluation of an adhesive having CDM characteristics by heat were performed. |
