                    When waterborne polyurethane is used as adhesive, it must be mixed generally. Based on waterborne polyurethane, crosslinking agent, thickening agent, filler, plasticizer, pigment and other additives can be added. Other types of waterborne resin and water can be added.In order to obtain higher resistance to water Heat resistance and bonding strength, at present a lot of waterborne polyurethane syst...
