What is crosslinking of waterborne polyurethane? The molecular chain of waterborne polyurethane resin is generally linear or branched, and the strength of the film without crosslinking is lower. In order to improve the water resistance, chemical resistance, high temperature resistance and mechanical properties of the cured film, it is necessary to appropriately increase the degree of […]
