How does the ceiling fabric come off?
The top of the car is covered with polyurethane glue.
Polyurethane glue is the molecular chain containing ammonia ester and isocyanate glue, due to the presence of strong polar isocyanate and carbamate radicals, highly reactive, can be cured at room temperature, which has excellent adhesive properties to metals, rubber, glass, ceramics, plastics, wood, fabric, leather a variety of materials such as.
The main chain of polyurethane is very flexible, and its biggest characteristic is to withstand shock, vibration and bending fatigue. Its peeling strength is very high, especially its low temperature resistance is excellent, and it is the champion in the existing glue. Polyurethane glue is easy to process, can be cured at room temperature and heating, and has little influence on the thermal stress of different materials. It has been widely used in various fields. Polyurethane glue has poor water resistance and heat resistance, so it is necessary to pay attention to it when selecting.
