Problems solved by technology

[0003] Polyurethane glass glue has high strength, tear resistance, soft wear resistance, puncture resistance, oil resistance and medium corrosion resistance. It has been widely used in rail vehicles, automobiles, ships and other windshields, side windows and base iron plates and aluminum plates. Bonding and sealing, but the existing polyurethane glass glue has poor water resistance and weather resistance, and it is prone to yellowing and cracking when used outdoors or in a water environment, which seriously limits its application
