| 摘要 |
The present invention relates to aqueous polyurethane dispersions containing amide groups that are pendant to the backbone of the polyurethane, wherein the amide groups (calculated as NH-CO-, MW43) are present in an amount of 1 to 14% by weight, based on the weight of the polyurethanes.The present invention also relates to aqueous, one-component, thermoset compositions containing the polyurethanes with amide groups in the backbone and a cross-linking component that is reactive with amide groups. Finally, the present invention relates to coatings, sealants and adhesives prepared from these aqueous, one-component, thermoset compositions.
